    Abstract: 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.

    Abstract: Disclosed is a manufacturing method of a liquid crystal display device which is a manufacturing method of a liquid crystal display device including a liquid crystal alignment film to which an alignment regulating force is imparted by a photo-alignment treatment, including: a film forming step of forming a film containing a polymer whose main chain is cleaved by irradiation with light; a photo-alignment step of imparting an alignment regulating force to the film formed in the film forming step by irradiation of the film with light in an atmosphere of a temperature lower than 100° C.; and a removing step of removing a low-molecular weight component generated by cleaving the main chain of the polymer through the light irradiation after the light irradiation. Also disclosed is a liquid crystal display device manufactured by the manufacturing method.

    Abstract: A liquid crystal display device has a liquid crystal display panel including pixels each having an active device, a pixel electrode, a common electrode and a liquid crystal layer arranged in a dot matrix array. The liquid crystal display panel has a first substrate, a second substrate, and a liquid crystal layer provided between the first substrate and the second substrate. The first substrate has the active device, the pixel electrode, the common electrode and a first alignment film. The second substrate has a second alignment film. The first alignment film and the second alignment film are respectively a photo alignment film formed by irradiating a photo decomposition type insulating film with light. The second alignment film has a thickness of at least 10 nm and no greater 50 nm and is thinner than the first alignment film.

    Abstract: 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.
