Abstract: A pixel includes a light emitting element, a driving transistor configured to control a driving current provided to the light emitting element, and an initialization transistor configured to provide a first initialization voltage to a gate of the driving transistor, and turned on in response to an initialization gate signal. A voltage level of the first initialization voltage in a blank period of a low-frequency driving mode is higher than a voltage level of the first initialization voltage in the blank period of a high-frequency driving mode.

Abstract: A display device includes first and second data lines, first and second voltage lines, and a plurality of pixels. The plurality of pixels includes a first sub-pixel including a first pixel circuit and a first light emitting element and a second sub-pixel including a second pixel circuit and a second light emitting element. The first voltage line includes a (1-1)-th portion extending in a first direction and a (1-2)-th portion electrically connected to the (1-1)-th portion and extending in a second direction intersecting the first direction, and the second voltage line includes a (2-1)-th portion extending in the first direction and a (2-2)-th portion electrically connected to the (2-1)-th portion and extending in the second direction.
