Abstract
To provide a structure of an electrically stable step film of a columnar spacer, which can be formed in a region of a storage capacitor without increasing the number of steps. A liquid crystal display device of the present invention further includes, in all the pixels, step films of a same area formed with a semiconductor layer within a storage capacitor forming part. The pixels includes a kind in which the columnar spacer is provided at a position abutting against a step film forming part and a kind in which the columnar spacer is provided at a position away from the step film forming part.
