Abstract: The present invention provides an in-plane switching liquid crystal display (IPS-LCD) device that includes a substrate, a protrusive layer having many protrusions on the substrate and a transparent electrode on each of the protrusions. One may dispose a color filter on the protrusions and fill in liquid crystal material between the color filter and the substrate. In contrast to conventional IPS-LCD devices, the IPS-LCD device of the present invention does not require the use of spacers. The present invention may thus largely enhance the light penetration rate and simplify the manufacturing process.

Abstract: An IPS (in-plane switching) liquid crystal display has a color filter substrate (3), a TFT (thin film transistor) substrate (8), and a liquid crystal layer (7) interposed therebetween. The TFT substrate includes a TFT plate (5), a protrusion layer (6), and an electrode matrix. The electrode matrix includes a plurality of transversely disposed gate lines (22), a plurality of longitudinally disposed data lines (21), switching elements, a plurality of common electrodes (27), and a plurality of pixel electrodes (28). The protrusion layer has a plurality of protrusion portions (61). The common and pixel electrodes are formed on the protrusion portions in one-to-one correspondence to provide an array of protrusive electrodes that generate a strong and highly uniform parallel electric field. This provides better picture quality, and can lower power consumption and/or yield a higher aperture ratio.

Abstract: An LCD device (2) includes two substrates (21, 22), a liquid crystal layer (27) therebetween, and gate lines (24) and data lines (23) formed on one substrate thereby defining pixel regions. A set of pixel electrodes (26) and a set of common electrodes (25) are provided in each pixel region. A first subset of the pixel electrodes and a first subset of the common electrodes are disposed parallel to each other in alternating fashion and extend along a first horizontal axis, a second subset of the pixel electrodes and a second subset of the common electrodes are disposed parallel to each other in alternating fashion and extend along a second horizontal axis, and the first and second axes are inclined at respective angles relative to the data lines. Thus when voltage is applied, liquid crystal molecules are twisted in two different directions (281, 282) so as to reduce color shift.

Abstract: An IPS LCD includes a first substrate (21), a second substrate (22), and a liquid crystal layer (23) between the first and second substrates. The first substrate includes a first polarizer (210), a first transparent plate (211) and a color filter layer (212) stacked one on the other from top to bottom in that order. The second substrate includes a second polarizer (220), a second transparent plate (221), an insulating layer (222), a passivation layer (224) and an alignment layer (225) stacked one on the other from bottom to top in that order. A data line (226) is disposed on the second transparent plate, and is covered by the insulating layer. A pixel electrode (223) and a common electrode (227) are separately disposed on the passivation layer, and are covered by the alignment layer. The symmetry of the pixel and common electrodes enables the IPS LCD to eliminate the image sticking phenomenon.

Abstract: An active matrix liquid crystal display includes a first glass layer (210), a second glass layer (220) opposite to the first substrate, a liquid crystal layer (27) disposed between the two glass layers, at least one alignment layer disposed between the two glass layers, a number of common electrodes (225) arranged on the second glass layer, an insulation layer (227) disposed on the second glass layer and the common electrodes, a number of pixel electrodes (226) arranged on the insulation layer, and a passivation layer (221) formed on the insulation layer and the side of the pixel electrodes. The common electrodes and pixel electrodes are formed at intervals. A gap between the common electrodes and the liquid crystal layer is equal to that between the pixel electrodes and the liquid crystal layer.

Abstract: An IPS (in-plane switching) liquid crystal display (2) has a first substrate (23), a second substrate (24) opposite to the first substrate, a liquid crystal layer disposed between the two substrates, a plurality of common electrodes (25) and pixel electrodes (26) disposed on the second substrate, and a plurality of spacers (29) disposed on the common electrodes and the pixel electrodes. The spacers are electrically conductive. The liquid crystal layer, together with the electric field generators comprising the electrodes and the spacers connected with them, cooperatively form a “functionally unified” configuration. Accordingly, liquid crystal molecules (27) in the liquid crystal layer are in a strong electric field having a highly uniform direction. The strong electric field enables the IPS type liquid crystal display to operate on a lower driving voltage, and/or to provide more space between the electrodes to yield a higher aperture ratio.

Abstract: An In Plane Switching liquid crystal display (2) includes a first substrate (22), a second substrate (21), a liquid crystal layer, a plurality of common electrodes (25) and pixel electrodes (26). The first substrate and the second substrate are disposed oppositely and spaced apart, and the liquid crystal layer is disposed therebetween. The common electrodes and the pixel electrodes are formed on the first substrate parallel. A plurality of conductive spacers (29) is formed on the common electrodes and the pixel electrodes. When a voltage is applied across the common electrode and the pixel electrode, an electric field substantially parallel to the first substrate and the second substrate is generated between the conductive spacers on the common electrode and the pixel electrode. The In Plane Switching liquid crystal display has a high aperture ratio and a low driving voltage.

The first substrate includes in turn a first transparent sheet (211) and an alignment film (213). The second substrate includes in turn a second transparent sheet (221) and an insulating layer (224). A plurality of electrodes (222) and a thin film transistor (223) is formed between the second transparent sheet and the insulating layer. The alignment film has an alignment structure (214) thereon. The IPS LCD is low cost and low power consumption.
