Abstract:
A light emitting display device with an integrated touch screen includes: a substrate which includes a display area in which a plurality of display pixels is disposed and a non-display area around the display area; a light emitting diode in the display area; an encapsulation unit which covers the display area and the non-display area; a touch electrode line on the encapsulation unit; a touch routing line which is disposed in the non-display area and is connected to the touch electrode line; a plurality of blocking structures which is disposed in the non-display area and is configured to enclose the display area; and a step compensation layer disposed between the encapsulation unit and the touch routing line; wherein the step compensation layer reduces a step caused by the plurality of blocking structures to reduce irregularities of a surface of the encapsulation unit.
