Light emitting display device provided with external connection terminal located at peripheral portions of a display area
Abstract:
A display apparatus capable of preventing thermal deterioration of an organic EL layer to improve a reliability without increasing a frame area thereof includes a display area, a circuit and wiring area, a pixel circuit common supply line, a contact hole, an external connection terminal, and an adhesion area. In the display area, EL devices and pixel circuits are arranged in a matrix. In the contact hole, a common voltage line and a transparent electrode electrically connected to an output of the EL device are electrically connected to each other. To the external connection terminal, an image signal, a control signal, and electric power are externally supplied. The contact hole and the common voltage line are disposed to surround a peripheral of the display area. To the pixel circuit common supply line, the electric power is supplied from the external connection terminal. In a peripheral portion of the display area where the external connection terminal is disposed, the pixel circuit common supply line is disposed outside the contact hole and the common voltage line with respect to the display area.
