    Abstract: A display device includes a plurality of pixels. Each pixel includes a first transistor including a first gate electrode, a first source region, and a first drain region, a second transistor connected to the first source region of the first transistor, a third transistor connected to the first gate electrode and the first drain region of the first transistor, a fifth transistor connected to the first source region of the first transistor, and a sixth transistor connected to the first drain region of the first transistor. The pixels include a first pixel and a second pixel disposed adjacent to each other. The first and second pixels share a fourth transistor connected to the third transistor of the first pixel and the third transistor of the second pixel, and share a seventh transistor connected to the sixth transistor of the first pixel and the sixth transistor of the second pixel.

    Abstract: A display device comprises a substrate including display and peripheral areas, a semiconductor element, a pixel structure, and a plurality of dummy patterns. The semiconductor element is disposed in the display area on the substrate, and the pixel structure is disposed on the semiconductor element. The dummy patterns which have stacked structure are disposed in the peripheral area on the substrate, and contain a material identical to a material constituting the semiconductor element. The dummy patterns are arranged in a grid shape in different layers, and each of the dummy patterns includes a central portion and an edge portion surrounding the central portion. The edge portions of dummy patterns which are adjacent to each other in the different layers among the dummy patterns are overlapped each other in a direction from the substrate to the pixel structure.
