摘要： A LCD device having a large pixel holding capacitance includes opposedly facing first and second substrates, and liquid crystal between them. The first substrate includes a video signal line, a pixel electrode, a thin film transistor having a first electrode connected to the video signal line and a second electrode connected to the pixel electrode, a first silicon nitride film formed above the second electrode, an organic insulation film above the first silicon nitride film, a capacitance electrode above the organic insulation film, and a second silicon nitride film above the capacitance electrode and below the pixel electrode. A contact hole etched in both the first and second silicon nitride films connects the second electrode and the pixel electrode to each other. A holding capacitance is formed by the pixel electrode, the second silicon nitride film and the capacitance electrode.

摘要： In a manufacturing method of a display device where a photosensitive material film formed on a light-transmitting film is divided into a plurality of small regions and the respective small regions of the photosensitive material film are sequentially exposed, it is possible to decrease the deviation of a focal point of light to be radiated to each small region. In exposing the photosensitive material film formed on the light-transmitting film, the whole exposure subject region of the photosensitive material film is divided into a plurality of small regions, and a focal point of light to be radiated to each small region is decided. The focal point of the light is decided such that the whole exposure subject region of the photosensitive material film is divided into a plurality of length measurement unit regions, and the focal point is determined based on a distance from an optical system of an exposure device to the photosensitive material film which is measured for every length measurement unit region, and an opaque conductive layer is formed in each length measurement unit region prior to the formation of the light-transmitting film.
