Abstract:
A liquid-crystal display device comprising:a liquid-crystal display panel with a liquid-crystal composition sandwiched between first and second substrates forming a pair; and a backlight unit for illuminating said liquid-crystal display panel from behind, wherein said first substrate includes a wiring section, switching elements, an insulating film formed so as to cover said wiring section and said switching elements, and pixel electrodes formed in a matrix on said insulating film and connected to said switching elements through contact holes made in said insulating film, and where the thickness of said insulating film provided between said wiring section and said pixel electrodes is c, the refractive index of said insulating film is nins, the thickness of said liquid-crystal composition layer is d, the refractive index of said liquid-crystal composition is nLC, and the angle at which the luminance in the direction of azimuth of said backlight unit becomes half of the front luminance is &thgr;, the amount a of overlap of said wiring section with said pixel electrodes is expressed as: a&gE;cÂ·tan[sinâˆ’1{(1/nins)sin &thgr;}]+(Â½)dÂ·tan[sinâˆ’1{(1/nLC)sin &thgr;}].
