Liquid crystal display device and method of manufacturing the same

A method for manufacturing a liquid crystal display device comprising the following steps of:

• providing a liquid crystal display cell having a pair of transparent substrates and a liquid crystal layer sandwiched between inner surfaces of the transparent substrates;
• reducing the thickness of the transparent substrates such that the outer surfaces of the transparent substrates have a first Ra surface roughness;
• and
• attaching an optical film on each of the outer surfaces of the transparent substrates by a transparent adhesive layer, wherein the transparent adhesive layer has an outer surface facing the optical film with a second Ra surface roughness which is smaller than the first Ra surface roughness.

A liquid crystal display device comprising:

• a pair of transparent substrates;
• a liquid crystal layer sandwiched between inner surfaces of the transparent substrates;
• and
• a transparent layer formed on the outer surfaces of transparent substrates, the transparent layer having an inner surface facing the transparent substrate and an outer surface opposing to the inner surface,
• wherein the outer surface of each transparent substrate has a first Ra surface roughness, and the outer surface of the transparent layer has a second Ra surface roughness which is smaller than the first Ra surface roughness.
