A liquid crystal display device realizing both a wide view angle and a high-quality image display without “coloring” or “letter blurs” comprises a front substrate, a rear substrate facing to the front substrate, a liquid crystal layer sandwiched between the front substrate and the rear substrate, a mirror-reflection layer disposed on the rear substrate, a single refraction layer provided on an outer surface of the front substrate, a polarizing plate provided on an outer surface of the single refraction layer, and a diffusing layer provided on an outer surface of the polarizing late to diffuse light from the single refraction layer.

A phase difference plate for delaying the phase of incident light by &lgr;/4 and a liquid crystal layer for shifting the incident light by &lgr;/2 in accordance with an applied voltage are interposed between a polarization plate and a selective reflecting layer made of a cholesteric liquid crystal. A color filter layer is formed on the polarization-plate-side of the selective reflecting layer. A back-surface light source for emitting light having intensity peaks in a plurality of predetermined wavelengths is located on the back-surface of the selective reflecting layer. The selective reflecting layer is formed to transmit almost all light components in the plurality of small regions including the plurality of predetermined wavelengths and reflect almost all light components in regions between the plurality of small regions.

A liquid crystal display element comprises a polarization plates, phase difference plates, a liquid crystal layer, and selectively reflective layers for reflecting part or whole of circularly polarized light in a specific direction. The products of the respective thicknesses of the polarization plate, phase difference plate, liquid crystal layer, and selectively reflective layer and the difference between an average refractive index in a direction perpendicular to each display plane and an average refractive index in a direction parallel to the display plane are set so that the absolute value of their sum total is 50 nm or less. Each selectively reflective layer is formed of a layer having positive refractive index anisotropy and a layer having negative refractive index anisotropy.

摘要:
An LCD device includes a transparent glass plate 122 and thin film transistor electrodes 124 formed on the glass plate 122. A photosensitive insulation film 128 is coated on the glass plate 122 and the thin film transistor electrodes 124. The insulation film 128 includes transparent and reflective regions 134 and 133 which are different in thickness. Light shielding films 126 are positioned underneath boundaries of the transparent and reflective regions 134 and 133. Where an optical exposure stage includes different reflection coefficient portions, the light shielding films 126 prevent light reflected by the exposure stage from reaching the insulation film thereby maintaining the accuracy of its patterning.
