Abstract

The object of the present invention is to provide a photoelectric device capable of effectively utilizing a light shielding layer for preventing control light from injecting to a semiconductor device. To achieve the object, the inventive liquid crystal display device is characterized in comprising: photoelectric material 50 sandwiched between a device substrate 10 of pixel electrode 9 and a counter substrate 20 opposite to the device substrate 10. The device substrate 10 includes: a semiconductor device 30 for driving the pixel electrode 9, insulating films 17 and 18 covering the semiconductor device 30, and a reflective plate 14 formed on the insulating films 17 and 18. The reflective plate 14 has an opening 14a. On the other hand, a light shielding layer 13 for shielding the light injecting to the semiconductor device 30 is formed on the side of device substrate 10 of the semiconductor device 30. The light shielding layer 13 has an opening 13a at substantially the same region as the opening 14a of the reflective plate 14.

Description

technical field [0001] The present invention relates to an electro-optical device and an electronic device including the electro-optical device, and particularly to a transflective (transmissive) reflective electro-optic device having a reflection plate on the inner surface of a substrate. Background technique [0002] As a conventionally known electro-optical device such as a liquid crystal device, an electro-optic material such as liquid crystal is sandwiched (interposed) between a pair of substrates, and at the same time, matrix-shaped pixel electrodes are formed on the substrates, and the pixel electrodes are controlled by TFT elements. An active-matrix type display device that can perform on-off display by power-on control. In a display device using such a TFT element, when light enters a channel region of the TFT element, an optical leakage current is generated, which may cause display defects such as a decrease in contrast and screen flickering. Therefore, for exampl...

Problems solved by technology

As described in Patent Document 1, if the light-shielding film is formed only corresponding to the formation region of the TFT element, there will be a step difference on the element substrate due to the formation region and the non-formation region, and the substrate spacing will become uneven in each region, and there will be The problem of uneven delay value

In addition, as described in Patent Document 2, the structure in which a light-shielding layer is provided on the substantially front surface of the TFT element substrate on the liquid crystal side cannot be applied to a transflective panel.

In addition, as described in Patent Document 3, the structure of providing a light-shielding layer on the source (electrode) line cannot be applied to a transflective panel.
