摘要： A display panel includes a plurality of display elements arranged in a display area, an opening, a multi-layer including a first layer and a second layer disposed on the first layer, and a groove. Each display element includes a pixel electrode, an emission layer disposed on the pixel electrode, and an opposite electrode disposed on the emission layer. The display area surrounds the opening. The groove is located between the opening and the display area. The groove has an undercut cross-section that is concave in a thickness direction of the multi-layer, the second layer includes a pair of tips that protrude toward a center of the groove, and a length of each tip is less than about 2 μm.

摘要： A display apparatus includes a thin film transistor disposed in a display area of a substrate and a display device in the display area that is electrically connected to the thin film transistor, an encapsulation layer that protects the display device, at least one through portion formed in the display area that vertically penetrates the substrate and a plurality of layers stacked on the substrate, and a first groove and a second groove that are spaced apart from each other and that surround the at least one through portion. A flow-restriction portion is disposed in a region between the first groove and the second groove that protrudes upwards from the substrate and confines an organic encapsulation layer of the encapsulation layer.

摘要： A display device capable of improving reliability (e.g., impact resistance) of a display panel having a through-hole, and a method of manufacturing a display device are provided. A display device includes: a camera module including a lens; a display panel including a through-hole overlapping the camera module on a plane; a window glass on the display panel; and a filling member in the through-hole and opposing each of the camera module and the window glass. A refractive index difference between an end portion of the filling member and the lens is about 0.7 or less, and a refractive index difference between another end portion of the filling member and the window glass is about 0.5 or less.

摘要： An electrowetting display device including a display panel that includes a display area in which a plurality of pixels is partitioned by a partition wall and a non-display area, a data driver that applies data voltages to the pixels through a plurality of data lines, and a gate driver disposed in the non-display area to apply gate signals to the pixels through a plurality of gate lines. The pixels receive the data voltages in response to the gate signals and display gray scales corresponding to the data voltages, and the partition wall is extended in the non-display area to cover the gate driver.
