Abstract: In a semi-transmissive liquid crystal display device, the thickness of liquid crystal layer in the reflective region can be adjusted by controlling the film thickness of the organic insulating film for reflection and the film thickness of the color layer for reflection. Furthermore, the thickness of liquid crystal layer in the transmissive region can be adjusted by controlling the film thickness of the organic insulating film for transmission and the film thickness of the color layer for transmission. Since the thicknesses of liquid crystal layer in the reflective region and that in the transmissive region can be adjusted, the reflectance in the reflective region and the transmittance in the transmissive region can each be set at the most appropriate values.

Abstract: To provide a structure and a manufacturing method which can manufacture, at a low cost and with good yield, a liquid crystal display panel having a lenticular lens and a substrate formed in a unified manner. When forming a lenticular lens onto a mother CF substrate by using a wet etching method, substrates are dipped into an etching solution while being raised up in such a manner that the length direction of slit openings of a mask is aligned with a vertical direction and an area having no mask pattern comes on a bottom side. With this, the residuals generated due to glass impurities can be drained towards the lower side along the lenticular lens shape to be discharged to the flat area, which makes it possible to suppress deterioration in the etching processed shape.

Abstract: A liquid crystal display is fabricated which has bus wires disposed in a grid shape, switching elements coupled to the bus wires, and pixel electrodes which are disposed on an interlayer insulating film formed by coating and which are coupled with the switching elements. In fabricating the liquid crystal display, when a transparent conductive film is formed on the interlayer insulating film which is formed by coating, the temperature of the substrate is controlled to become 100° C.-170° C. In another embodiment, when the transparent conductive film is formed on the interlayer insulating film in a non-heated condition, an oxygen flow rate ratio is set to 1% or lower, and annealing is performed after forming the film. Thereby, when etching the ITO film on the interlayer insulating film, etching residue is not produced. Further, contact resistance between the ITO film and the lower layer metal can be uniformly decreased, and display defects can be obviated.
