Claim Text:
1. A liquid crystal display device comprising: a TFT substrate having a pixel electrode and a counter electrode with an inorganic insulating film therebetween, and a first alignment film of organic material formed on part of the inorganic insulating film; a counter substrate having an overcoat film, which is an organic material, formed on a black matrix and color filter, the counter substrate having a second alignment film of organic material formed directly on the overcoat film; and a seal portion including a sealant; wherein the TFT substrate is bonded to the counter substrate by the sealant; wherein the liquid crystal molecules are sandwiched between the TFT substrate and the counter substrate and controlled by an electric field generated between the pixel electrode and the counter electrode of the TFT substrate; wherein the first alignment film is not provided at the seal portion, and the sealant is bonded to the inorganic insulating film of the TFT substrate; wherein, in a cross-section perpendicular to a side of the counter substrate, the sealant is bonded to the second alignment film of the counter substrate at a first part of the seal portion corresponding to an outer side portion including an outer edge of the sealant and at a second part corresponding to an inner side portion of the sealing portion; wherein, in the cross-section perpendicular to the side of the counter substrate, the sealant is bonded to the overcoat film of the counter substrate where the second alignment film is not provided at another part of the seal portion other than the first and second parts of the seal portion; and wherein the first alignment film and the second alignment film of the organic material are responsive to optical alignment for forming anisotropy therein.
