Problems solved by technology

[0007] However, in the sub-pixel, the pixel switching element electrically connected to the pixel electrode and various wirings are configured as a light-shielding region that does not transmit light, and there is a limit to reducing the area occupied by the light-shielding region. Therefore, in the existing configuration, There is a problem that it is difficult to increase the pixel aperture ratio as described above

[0043] (overall composition)

[0044] figure 2 It is a block diagram showing an electrical configuration of an electro-optical device to which the present invention is applied. Such as figure 2 As shown, the electro-optical device 100 is roughly composed of a liquid crystal panel 100p, an image processing circuit 202, a timing generating circuit 203, and a power supply circuit 201. The image processing circuit 202, the timing generating circuit 203, and the power supply circuit 201 are installed on the The flexible substrate (not shown) of the IC and other components. In the timing generation circuit 203, a dot clock for driving each pixel 100a (sub-pixel 100b) of the liquid crystal panel 100p is generated, based on the dot clock, clock signals VCK, HCK are generated, and the clock signals VCKB, HCK are inverted and transmitted. Start pulse HSP, VSP. The image processing circuit 202, when image data is input from the outside, generates an image signal based on the input ...

Embodiment approach 2

[0068] Figure 6 It is an explanatory diagram showing a planar arrangement of pixels (sub-pixels) in the electro-optical device 100 according to Embodiment 2 of the present invention. In addition, since the basic configuration of this embodiment is the same as that of Embodiment 1, the same parts are shown with the same symbols and their descriptions are omitted.

[0069] Such as Figure 6 As shown, also in the electro-optical device 100 of this embodiment, one pixel 100a is constituted by two sub-pixels 100b.

Abstract

The present invention relates a photoelectric device and electronic device. Through forming pixel with a form corresponding with display, a photoelectric device which can display various information with a high brilliance, and an electronic device comprising the photoelectric device are provided. When the photoelectric device is used for a head-up display, through forming one pixel (100a) by two sub-pixels (100b), a first sub-pixel (100b1) in two sub-pixels (100b) is taken as a color-using sub-pixel corresponding to red color (R), and a second sub-pixel (100b2) is taken as a color-using sub-pixel corresponding to green color (G). According to the composition, as two sub-pixels (100b) form the pixel (100a), the thin-film transistor (30) and the electric wiring in the pixel (100a) account for little proportion, and the opening rate is high.

Description

technical field [0001] The present invention relates to an electro-optical device capable of displaying various information in color, and electronic equipment including the electro-optic device. Background technique [0002] In electro-optical devices such as liquid crystal devices and organic electroluminescence devices, a plurality of pixels are arranged in a predetermined direction. In the case of performing color display with, for example, a liquid crystal device among such electro-optical devices, as Figure 11 As shown in (a), a plurality of pixels 100e are composed of three sub-pixels 100f(R), 100f(G), and 100f(B) corresponding to red, green, and blue, respectively (see Patent Document 1). [0003] In addition, in medical display devices, etc., for the purpose of drawing characters and symbols on images, such as Figure 11 As shown in (b), it is proposed to use one sub-pixel 100f(C) of the three sub-pixels 100f constituting the pixel 100e for color display and two sub...
