摘要： PURPOSE:To suppress the blurring of the electric latent image patterns formed on a photoconductive layer and to improve the resolving power of the liquid crystal display element by disposing a semiconductor layer having low mobility or a semiconductor layer having a high defect level density on a liquid crystal layer side. CONSTITUTION:A first hydrogenated amorphous silicon film 31 and a second hydrogenated amorphous silicon film 32 are successively formed on a transparent conductive film 2 and the photoconductive layer 30 is formed of both these layers. The other surface of the second hydrogenated amorphous silicon film 32 is integrated with a reading-out reflection film 6. The second amorphous silicon layer 32 nearest the liquid crystal layer 4 is at least either of the layer which is higher in the defect level density incorporated into the layer than the other semiconductor layer and the layer having the small carrier mobility in the layer. Then, the blurring of the carriers accumulated between the photoconductive layer 30 and the liquid crystal layer 4 at the time of writing in an intra-surface direction is suppressed by the action of the second amorphous silicon layer 32 and consequently, the higher resolving power of the liquid crystal light valve is obtd.

摘要： PROBLEM TO BE SOLVED: To obtain a reflective liquid crystal display with a high contrast ratio and high brightness. SOLUTION: In the liquid crystal display, alignment films are formed on two substrates 2a, 2b which have transparent electrodes 3a, 3b respectively. A cell with a 10 μm cell gap is formed by confronting and sticking the two substrates 2a, 2b so as to hold directions of alignment in parallel orientation. A liquid crystal layer 4 is formed by injecting a GH(guest-host) liquid crystal material (about 10 dichroic ratio, 3.0% dyestuff concentration, +5.5 dielectric anisotropy) into the cell. A birefringent film with 120 nm birefringence and a film vapor-deposited with aluminum are stuck to a side opposite to a display surface (a side of the substrate 2b) of the cell to form a birefringent layer 6 and a reflective layer 8 in turn.

摘要： PROBLEM TO BE SOLVED: To obtain a liquid crystal display device which allows driving with a low voltage and has excellent display characteristics. SOLUTION: Comb-shaped pixel electrodes 11 and common electrodes 12 are arranged on a substrate 13 and a counter substrate 14 in such a manner that the teeth of respective combs are paralleled and alternated with each other. When voltage is impressed on the liquid crystal display device, an electric field in a diagonal direction is generated by the pixel electrodes 11 and the common electrodes 12 and liquid crystal molecules 10b having positive dielectric anisotropy are oriented along the electric field in a diagonal direction. The pixel electrodes 11 and the common electrodes 12 are preferably arranged by parting the spacings therebetween in such a manner that the electric field in a diagonal direction is made more nearly horizontal in order to eliminate the dependence of the liquid crystal molecules 10b on visual field angles. On the other hand, a higher driving voltage is made necessary in order to make the inter-electrode spacing larger. Then, the angle A formed by the electric field direction with the substrate surface with respect to the liquid crystal display device having a cell gap of 4 to 10μm is set larger than 20 deg. and below 45 deg..
