    Abstract: A display device can include a base, a plurality of pixels in a matrix along first and second directions intersecting each other in a display area on the base, control signal lines to supply a control signal to the pixels, and power supply lines to supply an initialization voltage to the pixels. Each pixel can include a pixel circuit having a plurality of transistors and a light emitting element drivable by the pixel circuit. The plurality of transistors can include a first transistor between the power supply line and the light emitting element. The first transistor can be controlled based on the control signal. The control signal lines, which can extend to connect to the plurality of pixels, can be arranged in the second direction. The power supply lines, which can extend to connect to the plurality of pixels, can be arranged in the first direction.

    Abstract: A display device includes a planarization layer on a substrate, a pixel with an organic electroluminescence element on the planarization layer, a sealing layer covering the pixel, a terminal electrode arranged at an edge of the substrate, and a first wiring arranged over the sealing layer and electrically connected to the terminal electrode. The planarization layer has an outer edge that forms a step over the substrate between the pixel and the terminal electrode. The first wiring extends from above the sealing layer to intersect with the step. In a plan view, the step has a first protrusion of the planarization layer protruding in a direction of the terminal electrode, a second protrusion adjacent to the first protrusion and protruding in a direction of the terminal electrode, and an intermediate region between the first protrusion and the second protrusion.
