Abstract:
A liquid crystal display panel substantially free of a display unevenness due to a glass substrate warpage, said liquid crystal display panel comprising:a first glass substrate and a second glass substrate opposed to each other; a liquid crystal material filling the space between said first and second glass substrates; a first polarizer film which is disposed on the outside surface of said first glass substrate and which comprises at least a polyvinyl alcohol layer and a triacetyle cellulose layer; and a second polarizer film which is disposed on the outside surface of said second glass substrate and which comprises at least a polyvinyl alcohol layer and a triacetyle cellulose layer, wherein said first glass substrate and said first polarizer film are attached to each other and said second glass substrate and said second polarizer film are attached to each other by a process such that said first glass substrate and said second glass substrate have substantially no warpage due to a stress from said first polarizer film and said second polarizer film, respectively, said first and second polarizer films having been attached on said first and second glass substrates, respectively, after heating said first and second polarizer films at a first predetermined temperature and for a first predetermined time, said first predetermined temperature and said first predetermined time having been selected to substantially relax said first polarizer film and said second polarizer film by removing moisture from said first polarizer film and said second polarizer film.
