Claim:
1. A liquid crystal display device comprising: a plurality of pixels disposed in a matrix shape, each pixel having insulating wall-shaped structures at the boundaries of the pixels and a smaller wall-shaped structure between the wall-shaped structures; wall electrodes, each having wall-shaped electrodes formed on the side faces of the wall-shaped structures at the boundaries of the pixels, and planar electrodes that are connected to the wall-shaped electrodes and extend in the planar direction from faces where the wall-shaped electrodes are in contact with a substrate; electrodes, each having a TFT-side electrode covering the small wall-shaped structure and a storage capacitor electrode that is connected to the TFT-side electrode and extends in the planar direction of the substrate; and an interlayer insulating film formed between the storage capacitor electrodes and the planar electrodes, wherein the interlayer insulating film does not exist at each of a plurality of connection parts between the wall-shaped electrodes and the planar electrodes, the thicknesses of the wall electrodes at the plurality of connection parts between the wall-shaped electrodes and the planar electrodes are formed to be larger than the wall-shaped electrodes, and the planar electrodes have portions where the thicknesses are less than the thicknesses of the wall-shaped electrodes at the plurality of connection parts between the wall-shaped electrodes and the planar electrodes.
