Abstract: A display device may includes: a substrate including a pixel area and a peripheral area; pixels provided in the pixel area of the substrate, each of the pixels including a light-emitting element provided with a pixel electrode; scan lines and data lines coupled to the pixels; a power line configured to supply driving power to the light-emitting elements, and extending in one direction; and an initialization power line configured to supply initialization power to the light-emitting elements. The power line and the initialization power line may be provided on different layers. The initialization power line may include: first conductive lines extending in a direction oblique to the scan lines and the data lines; and conductive lines intersecting the first conductive lines. The first and second conductive lines may be disposed in areas between the pixel electrodes of adjacent light-emitting elements.

Abstract: An emission driver according to example embodiments includes a plurality of stages each having an input block; an output block; a first signal processing block controlling a voltage of a first node; a second signal processing block controlling a voltage of a fourth node in response to the signal supplied to a third input terminal and a voltage of a fifth node; a third signal processing block controlling the voltage of the fourth node; a fourth signal processing block controlling the voltage of the third node; and a stabilization block electrically connected between the input block and the output block to limit a voltage drop between the first node and the third node. The stabilization block may limit a voltage drop between a second node and the fourth node by lowering a voltage of a second power source to the fifth node.
