摘要
A liquid crystal display device having a pair of substrates, at least one of which is transparent, a liquid crystal layer interposed between the pair of substrates, an electrode structure formed on one of the pair of substrates for generating an electric field in said liquid crystal layer, the electrode structure including at least one common electrode and at least one pixel electrode, a gate insulating film formed on the one common electrode, an insulation layer formed on the gate insulating film and an orientation film formed on the insulation layer. A sum of thickness of the gate insulating film, the insulation layer and the orientation film is no greater than about 2.8 .mu.m.
