Abstract: A light guide plate (32) for a backlight module includes a light incident surface (321), a bottom surface (323), and a plurality of light guide elements (320) disposed therein. Each light guide element has a light refractive surface (324) opposite to the light incident surface. An angle between the light refractive surface and the bottom surface is an acute angle. A refractive index of each light guide element is different from that of adjacent light guide elements. The reflectivity index of the light guide element and the angle can be selected and arranged so that most if not all the light beams are emitted from the light output surface. Thereby, the light guide plate is highly efficient in the utilization of light beams.

Abstract: An LCD device (2) includes a first substrate (21), a second substrate (22), and a liquid crystal layer (23) having liquid crystal molecules is interposed between the first and second substrates. A pretilt angle of the liquid crystal layer adjacent to one of the substrates is 0° to 15°, and a pretilt angle of the liquid crystal layer adjacent to the other substrate is 75° to 90°. This ensures that the LCD device provides a good quality display. In addition, the alignment and the pretilt angle of the liquid crystal molecules means that the liquid crystal molecules are hybrid aligned when this is needed, and can be twisted in a very short time.

Abstract: A multi-domain IPS (in-plane switching) liquid crystal display (20) includes a first substrate (201), a second substrate (202), liquid crystal molecules (203) filled between the first and second substrates, and gate lines (211) and data lines (212) formed on the first substrate. The gate lines and data lines define pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (233), common electrodes (243), and a TFT (thin film transistor) (220). The pixel electrodes and the common electrodes have a same curved shape, and are uniformly spaced apart from each other. Therefore the electric field generated by them is a smooth continuum of multiple domains, and the visual performance at various different viewing angles is equally good. Because the pixel and common electrodes do not have sharp bends, disclination is avoided. Therefore the IPS liquid crystal display has a high contrast ratio.
