摘要： Manufacture of a liquid crystal display is disclosed. The liquid crystal display includes a backlight unit, a backlight unit-side polarizing plate, and a liquid crystal cell held by two glass plates, the liquid crystal cell having an electrode, a liquid crystal layer, an alignment layer, and a color filter arranged between the glass plates. The liquid crystal display also includes a transparent front plate arranged at a side of the liquid crystal cell opposite to the backlight unit, a polarizing plate attached to the liquid crystal cell, and a transparent organic medium layer arranged between the front plate and the liquid crystal cell. Since the front plate is provided at the outermost surface of an image display portion, and the transparent organic medium is filled between the front plate and the liquid crystal module, it is possible to achieve an improvement in wear resistance and a reduction in reflectance.
