Claim:
1. A liquid crystal display device comprising: a TFT substrate including a display area with pixels arranged in a matrix form, each pixel including a pixel electrode and a TFT, in which an alignment film is formed; a counter substrate disposed opposite the TFT substrate; and a liquid crystal interposed between the TFT substrate and the counter substrate, wherein the alignment film includes a lower alignment film and an upper alignment film that is stacked on the lower alignment film and contacts with the liquid crystal, wherein the upper alignment film is subjected to photo alignment treatment, wherein a material of the lower alignment film and a material of the upper alignment film are polyimide, wherein a bulge with an increased film thickness is formed at an end portion of the lower alignment film, and wherein an end portion of the upper alignment film is present on a side closer to the display area than the bulge of the lower alignment film.
