摘要： A pixel is formed by sealing an insulating liquid and floating particles in an area defined by a first substrate, a second substrate and partitions. The width of the partition has to be reduced in order to improve the pixel brightness by enlarging a flat electrode. In this case, the height of the partition has to be reduced for retaining the mechanical strength. If the height of the partition is reduced, an area of the partition electrode becomes small, thus failing to retain the memory effect. The planar surface of the partition is then formed into a zigzag shape so as to increase the area of the partition electrode.

A liquid crystal display device includes a first substrate, a second substrate arranged to face the first substrate in an opposed manner, and liquid crystal sandwiched between the first substrate and the second substrate. The first substrate includes a video signal line, a pixel electrode, a thin film transistor having a first electrode thereof connected to the video signal line and a second electrode thereof connected to the pixel electrode, a first silicon nitride film formed above the second electrode, an organic insulation film formed above the first silicon nitride film, a capacitance electrode formed above the organic insulation film, and a second silicon nitride film formed above the capacitance electrode and below the pixel electrode. The second silicon nitride film is a film which is formed at a temperature lower than a forming temperature of the first silicon nitride film. The first silicon nitride film and the second silicon nitride film form a contact hole therein by etching both of the first silicon nitride film and the second silicon nitride film collectively by dry etching. The second electrode and the pixel electrode are connected to each other via the contact hole. A potential different from a potential applied to the pixel electrode is applied to the capacitance electrode, and a holding capacitance is formed by the pixel electrode, the second silicon nitride film and the capacitance electrode.
