Abstract

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.
