Abstract

PURPOSE:To obtain a display device of good display contrast and high rates of response despite the small thickness of its panel by roughening the liquid crystal side surface of at least one of two sheets of opposite glass substrates within a range of specific roughness. CONSTITUTION:The liquid crystal side surfaces of glass substrates 3, 3 are subjected to a 25% hydrofluoric acid treatment or polishing and are roughened within an Rmax 0.01-3mu range. Transparent conductive films 2, 2 are formed on the roughened surfaces and are subjected to orientation treatment thereon with polyvinyl alcohol or the like. Next, these are sealed to form a thin gap of about 5mu panel thickness, into which a liquid crystal is injected and sealed. Further, polarizing plates 4, 4 are stuck together on both surfaces of the panel, and a reflection plate 5 is provided to one of these, whereby the display device is obtained. By the roughening of the substrates 3, 3, the interference of light that occurs when the substrates 3, 3 is smooth is eliminated despite the small thickness of the liquid crystal layer 1, the quality of display is improved, contrast is improved and the rate of display response is increased.
