Abstract:
1. A liquid crystal display device comprising: a TFT substrate and a counter substrate; a liquid crystal layer disposed between the TFT substrate and the counter substrate; a plurality of scanning lines and a plurality of signal lines formed on the TFT substrate; a first insulation film formed above the plurality of scanning lines, the plurality of signal lines, and the TFT substrate; a first electrode formed on the first insulation film; a second insulation film formed on the first insulation film and the first electrode; a second electrode formed on the second insulation film; and an alignment film formed on the second electrode and the second insulation film, wherein the liquid crystal layer is driven by an electric field generated between the first electrode and the second electrode, wherein the second insulation film has a first portion disposed above the plurality of scanning lines or the plurality of signal lines; a distance from the TFT substrate to an upper surface of the second insulation film at the first portion is greater than a distance from the TFT substrate to an upper surface of the second electrode, wherein the alignment film comprising; a first part subject to photo-alignment treatment formed by a first precursor, a second part mechanically stronger than the first part formed by a second precursor, a thickness of the alignment film on the first portion of the second insulating film is thinner compared to a thickness of the alignment film on the second electrode, and a percentage of the second part in the alignment film on the first portion of the second insulation film is bigger compared to a percentage of the second part in the alignment film on the second electrode.
