Abstract: A method for controlling a curvature of a display device as a control method of the curvature of the display device including a flexible display panel, a curvature change member, a controller, and a photo sensor includes: measuring an amount of a light incident to the flexible display panel by using a photo sensor; confirming a position of a part where the amount of the measured light is more than a predetermined reference value in the flexible display panel when the amount of the measured light is more than the reference value; and changing the curvature around the part where the amount of the measured light is more than the reference value in the flexible display panel by using the curvature change member.

Abstract: A light emitting display device includes: a substrate; a transistor disposed on the substrate; an anode connected to the transistor; an emission layer disposed on the anode; a common voltage line disposed on the substrate; and a cathode disposed on the emission layer and the common voltage line, where a thickness of a first portion of the cathode overlapping the emission layer is different from a thickness of a second portion of the cathode not overlapping the emission layer.
