摘要:
A gate driver is implemented that includes an easily testable shift register to improve panel yields. In a monolithic gate driver including a shift register that operates based on 4-phase clock signals, each stage of the shift register is provided with an inter-stage connecting wiring line for receiving a clock signal other than clock signals received from a clock signal trunk wiring line, from a different stage than the stage; and a contact that connects a wiring line formed on the stage to the inter-stage connecting wiring line. The shift register is grouped every four consecutive stages. Markings formed of different numbers of planar-view circular-shaped structures are formed on bistable circuits of four stages included in each group such that the same type of marking appears every four stages.

A bistable circuit includes an output terminal that outputs a state signal, an output terminal that outputs an other-stage control signal, a first node of which a potential is controlled based on a set signal and a clear signal, a thin-film transistor that provides a potential of a second clock to the output terminal when a potential of the first node is at a high level, a thin-film transistor that provides a potential of a first clock to the output terminal when a potential of the first node is at a high level, and a thin-film transistor for changing a potential of the other-stage control signal to a low level based on a reset signal. The first clock is generated by a power source of a different system from the second clock, and has a smaller amplitude than that of the second clock.

A multi-primary color display device is capable of handling an increased number of primary colors for color image display with a reduced number of external parts, with reduced increase in the amount of drive circuit and reduced increase in operating speed. An active matrix liquid crystal panel includes a display section constituted by pixel formation portions, each made of four sub pixel-formation portions which handle four primary colors. These four sub pixel-formation portions are arranged in a 2×2 matrix pattern. With such a pixel configuration, a source driver drives as many as M source lines, which is two times the number M of pixels arranged in a horizontal direction. A gate driver is formed on the liquid crystal panel integrally with pixel circuit in the display section, and drives as many as N gate lines, which is two times the number N of the pixels arranged in a vertical direction.

An object of the present invention is to provide a multi-primary color display device which is capable of handling an increased number of primary colors for color image display with a reduced number of external parts, with reduced increase in the amount of drive circuit and reduced increase in operating speed. An active matrix liquid crystal panel (600) includes a display section (500) constituted by pixel formation portions, each made of four sub pixel-formation portions (Ps) which handle four primary colors. These four sub pixel-formation portions are arranged in a 2×2 matrix pattern. With such a pixel configuration, a source driver (300) drives as many as M source lines (Ls), which is two times the number Mpix of pixels arranged in a horizontal direction. A gate driver (400) is formed on the liquid crystal panel (600) integrally with pixel circuit in the display section (500), and drives as many as N gate lines (Lg), which is two times the number Npix of the pixels arranged in a vertical direction.
