Abstract: A display device includes a substrate including a first pixel region and a second pixel region having a smaller area than the first pixel region. The second pixel region is connected to the first pixel region. A first pixel is provided in the first pixel region and a second pixel is provided in the second pixel region. A first line is connected to the first pixel and a second line is connected to the second pixel. A dummy unit overlaps at least one of the first line and the second line, and compensates for a difference in load values between the first and second lines.

Abstract: A display device includes: a substrate; pixels, the pixels each including at least one transistor and a light emitting device connected to the transistor; data lines and scan lines connected to the pixels; and a power line supplying power to the light emitting device. The transistor includes an active pattern on the substrate, source and drain electrodes each connected to the active pattern, a gate electrode on the active pattern, an interlayer insulating layer covering the gate electrode, the interlayer insulating layer including a first interlayer insulating layer, a second interlayer insulating layer, and a third interlayer insulating layer, which are sequentially stacked, and a protective layer provided on the interlayer insulating layer. The third interlayer insulating layer includes a concave part in a region in which the light emitting device and the second conductive layer overlap with each other, and the second conductive layer is in the concave part.

Abstract: A display device includes first pixels in a first pixel area, second pixels in a second pixel area, first stages, second stages, and third stages. The first pixels are electrically connected to first signal lines, second signal lines, and data lines. The second pixels are electrically connected to at least a portion of third signal lines, fourth signal lines, or data lines. The first stages supply a first signal to the first and third signal lines. The second stages supply a second signal to the second signal lines and at least one of the fourth signal lines. The third stages supply the second signal to the fourth signal lines other than the at least one fourth signal line connected to the second stages. The second stages are spaced from the third stages.

Abstract: A display device includes a substrate including a display configured to display an image and a non-display area disposed on at least one side of the display area. A plurality of pixels is disposed in the display area. An organic insulating layer is disposed on the substrate. A pixel defining layer is disposed on the organic insulating layer. A sealing layer at least partially covers the display area and the non-display area and includes an inorganic material. The organic insulating layer and the pixel defining layer have a valley disposed therein. The valley is formed by removing portions of the organic insulating layer and the pixel defining layer along a circumference of the display area.
