Abstract

To achieve a display device that is suitable for increasing in size and to provide a high-resolution display device. In the display device, three or more adjacent gate lines are supplied with the same selection signal. Three or more pixels that adjoin in the column direction are connected to different source lines. In each of the pixels, a transistor including a semiconductor layer is disposed. An inner source line among three or more source lines is disposed to overlap with a conductive layer that functions as a pixel electrode. Part of the semiconductor layer of the transistor is provided between the outer source line and a source line adjacent to the outer source line.
