Abstract: A display device includes a display panel including light-emitting regions and an input sensor disposed on the display panel and including sensing patterns. The sensing patterns include mesh lines defining opening regions respectively overlapping the light-emitting regions and protruding portions having a shape protruding from at least one of the mesh lines into the opening regions. The protruding portions include a first protruding portion disposed between light-emitting regions spaced apart from each other by a first distance in a first direction and a second protruding portion which is disposed between light-emitting regions spaced apart from each other by a second distance smaller than the first distance in the first direction and has a smaller area than the first protruding portion in a plan view, thereby exhibiting excellent display quality and viewing angle characteristics.

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.
