Liquid-crystal display apparatus including a backlight section using collimating plate

A liquid-crystal display apparatus having a liquid-crystal display panel, a backlight section that uses a collimating plate to have collimated light launched into said liquid-crystal display panel and a light diffusing plate that diffuses the image-bearing light that has passed through said liquid-crystal display panel, said apparatus satisfying the following relation:

• d×tan θ≦A
• where θ is a divergence angle of said collimated light, d is a distance from the light diffusing plate to an interface in a liquid-crystal layer of said liquid-crystal display panel which is directed to the light diffusing plate, and A is a pixel size of said liquid-crystal display panel.
