Abstract:
A display apparatus includes a display area, in which pixels each including an EL device and a pixel circuit are arranged in a matrix on a substrate, and a column control circuit for controlling the pixel circuit column by column. The EL device is disposed between a lower pixel electrode and an upper transparent electrode on the substrate. The pixel electrode is electrically connected to the pixel circuit, and the transparent electrode is electrically connected to a common interconnecting line via a contact hole. The contact hole and the common interconnecting line are disposed to surround a periphery of the display area. The column control circuit is divided into two circuits one of which is disposed between the contact hole and the display area and the other of which is disposed outside the area between the contact hole and the display area.
