摘要： A liquid crystal display device includes a TFT substrate and a counter substrate and a liquid crystal layer sandwiched therebetween. A scanning line, a video signal line, a thin film transistor connected to the scanning line and the video signal line, a pixel electrode connected to the thin film transistor, and a counter electrode are formed on the TFT substrate, and a columnar spacer formed on the counter substrate. The pixel and counter electrodes are transparent, and the liquid crystal layer is controlled by an electric field generated between the pixel and counter electrodes. The counter electrode contacts with a metal line having a first part which is extended in parallel with the scanning line and a second part which is extended in parallel with the video signal line, a width of the first part of the metal line being narrower than a width of the scanning line.

摘要： An alignment film is given a 2-layer structure comprising a photoalignment film that is photoalignable and a low-resistivity alignment film whose resistivity is smaller than that of the photoalignment film. The photoalignment film is formed by a polyimide whose precursor is polyamide acid alkyl ester, the number molecular weight of the photoalignment film is large, and the stability of alignment of the photoalignment film by photoalignment is excellent. The low-resistivity alignment film is formed by a polyimide whose precursor is polyamide acid, the number molecular weight of the low-resistivity alignment film is small, and the resistivity of the low-resistivity alignment film is small. The 2-layer structure alignment film can be maintaining an excellent photoalignment characteristic, so DC afterimages can be controlled.
