A display device includes a substrate, a semiconductor layer on the substrate, a first insulating layer on the semiconductor layer, a first conductive layer on the semiconductor layer, a second insulating layer on the first conductive layer, a first contact hole penetrating the first insulating layer and the second insulating layer, a second conductive layer on the second insulating layer, connected to the semiconductor layer through the first contact hole, and including a hydrogen barrier material, and a third insulating layer on the second conductive layer.

Display device

A display device includes a substrate including a display area and a non-display area. First, second, and third insulating layers are sequentially disposed on the substrate. Pixels are disposed in the display area. Each of the pixels including a transistor and a light emitting element connected to the transistor. A data line is disposed in the display area. The data line is configured to supply a data signal to each of the plurality of pixels. A wiring portion is disposed in the non-display area. The wiring portion includes a connecting line connected to the data line and a fan-out line connected to the connecting line. A dummy pattern is disposed in the non-display area. The dummy pattern at least partially overlaps the wiring portion.

Display device having dummy pattern in non-display area

A display device includes: a first wiring line and a second wiring line separated from each other on a substrate; a gate insulating layer on the first wiring line and the second wiring line; a step difference compensation pattern between the first wiring line and the second wiring line on the gate insulating layer; a protective layer on the step difference compensation pattern; and a pixel electrode on the protective layer.
