Problems solved by technology

[0021] However, since the wiring of the power supply line LVDD for supplying the power supply voltage to the holding circuit 110 and the wiring of the ground line LVSS for supplying the ground voltage are performed, the wiring area increases and the pixel circuit cannot be miniaturized.
Therefore, the number of storage cells in the holding circuit 110 increases, leading to an increase in the size of the circuit, and it is difficult to promote high-definition pixels and multi-gradation.

Abstract

Subject of this invention is to provide a display device enabling multi-gradation display by reducing a wiring area of display pixels to micronize the pixels, and making a holding circuit to be of multiple bits. The wiring area is reduced by sharing a power supply line LVDD for supplying a power source voltage to the holding circuit 110 with an auxiliary capacitance line SCL connected with one of the electrodes of auxiliary capacitance 85. The auxiliary capacitance line SCL is arranged in parallel with a gate signal line 51 in a display pixel. The power supply lines of inverter circuits INV1, INV2 forming the holding circuit 110 are extended in the direction of crossing the auxiliary capacitance line SCL, and connected with the auxiliary capacitance line SCL. The shared auxiliary capacitance line SCL is fixed at the power supply voltage level (for example, 5 V).

Description

technical field [0001] The present invention relates to a display device, and particularly to a display device suitable for a portable display device. Background technique [0002] In recent years, portable display devices such as portable televisions, mobile phones, and the like have been demanded as market demands. In response to such demands, research and development has been actively conducted in order to meet the miniaturization, weight reduction, and power saving of display devices. [0003] Figure 5 A circuit configuration diagram of one display pixel of a conventional liquid crystal display device is shown in . A gate signal line 51 and a drain signal line 61 are formed to intersect on an insulating substrate (not shown in the figure), and a pixel selection thin film transistor 72 connected to the two signal lines 51 and 61 is provided near the intersection. . Hereinafter, the thin film transistor is simply referred to as TFT. The source 11s of the pixel selecti...
