Abstract
The present invention prevents electrostatic breakdown attributed to static electricity even in and after a cell cutting step. In a display device which includes a substrate, a plurality of pixels which is formed in a pixel part, a plurality of video lines which applies video voltages to the plurality of pixels, and a video voltage selection circuit which selects the video voltages to be inputted to the pixels and applies the selected video voltages to the predetermined video lines among the plurality of video lines, an electrostatic protective circuit for protecting a pixel part is connected to the plurality of video voltage inputting lines which inputs the video voltages to the video voltage selection circuit, and an electrostatic protective circuit for protecting a peripheral circuit is connected to the lines other than the video voltage inputting lines which is connected to the video voltage selection circuit. The electrostatic protective circuit for protecting the pixel part is connected between the plurality of video voltage inputting lines, and the electrostatic protective circuit for protecting the peripheral circuit is connected between the at least one video voltage inputting line and the line other than the at least one video voltage inputting line, between the plurality of lines other than the video voltage inputting lines, and between the line other than the at least one video voltage inputting line and a reference voltage line to which a reference voltage is applied.
