Claim Text:
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 picture signal lines formed on the TFT substrate; a first insulation film formed above the plurality of scanning lines, the plurality of picture 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 picture 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 comprises a first part subject to photo-alignment treatment, wherein the alignment film comprises a second part on the second electrode, and wherein the second part is disposed between the second insulation film and the first part, and wherein a precursor material of the first part and a precursor material of the second part are polyamide acid or polyamide acid ester, wherein a spacer is formed on the counter substrate and opposes to the first portion of the second insulation film, and wherein a spacer supporting base is formed on the TFT substrate and corresponds to the first portion and the spacer, when the thickness of the second part is defined as p1 and the thickness of the first part is defined as p2, p2/p1 over the first portion is smaller than p2/p1 over a second portion.
