Abstract
PURPOSE: To prevent unequal brightness by forming a light curtain by vapor deposition of a translucent reflection layer having nonuniform reflection patterns on a transparent glass substrate. CONSTITUTION: The light curtain 6 is formed by depositing Al by evaporation as the translucent reflection layer 62 having the nonuniform reflection patterns on the transparent glass substrate 61 and consists of such glass substrate and the vapor deposited layer of a thickness. Not only the Al but vapor deposited films of metal, such as chromium, as well are usable as the vapor deposited films. The translucent reflection layer 62 is deposited by evaporation on the transparent glass substrate 61 in such a manner, by which the deformation of the light curtain 6 and the change in the distance between the translucent reflection layer 62 and a light source 1 are prevented in the temp. range (0 to 40 deg.C) where the liquid crystal display element is used. As a result, the occurrence of the unequal brightness is prevented.
