Abstract: An object of this invention is to increase the number of liquid crystal display panels obtained from a mother substrate. There is provided a liquid crystal display device including a TFT substrate and a counter substrate bonded together by a seal portion formed along the periphery of the counter substrate, the TFT substrate having a terminal area formed in a portion thereof not opposed to the counter substrate. The TFT substrate has a bank-like organic passivation film formed along the edge of the terminal area. A stepped part is formed on the organic passivation film. The film thickness of the organic passivation film on the edge side of the stepped part is greater than the film thickness inside the stepped part.

Abstract: A liquid crystal display device has pixels in a TFT substrate, each of the pixels has a TFT. An organic insulting film 108 is formed to cover the TFT. A first electrode 109 and a second electrode 111 are formed above the organic insulting film 108 with an inorganic insulating film 110 placed between the first electrode 109 and the second electrode 111. An alignment film is formed on the first electrode 109 and the second electrode 111. The second electrode 111 connects with the TFT through a contact hole formed in the organic insulating film 108. A cross section of the organic insulating film 108 that includes the contact hole and is parallel to the second direction has a convex section and a concave section 70 at a bank located near the contact hole, the convex section being located closer to the contact hole than the concave section 70.

Abstract: A liquid crystal display device includes: a TFT substrate including a TFT, an organic passivation film formed to cover the TFT, and an alignment film; and a counter substrate including a spacer and an alignment film. The TFT substrate and the counter substrate are bonded with a sealing material in a seal portion, with a liquid crystal interposed between the two substrates. A wall-like structure is formed in the seal portion of the counter substrate, in a direction parallel to a side of the counter substrate. A concave portion of the organic passivation film is formed at a position corresponding to the wall-like structure of the TFT substrate, in a direction parallel to the side of the TFT substrate. With this structure, a gap between the wall-like structure and the TFT substrate is increased to facilitate the movement of the sealing material before curing, to form the sealing material uniformly.
