Abstract

According to one aspect of the invention, a display apparatus includes a substrate including a display area and a peripheral area around the display area, a thin film transistor in the display area including a semiconductor layer, a gate electrode, a source electrode, and a drain electrode, a first inorganic insulating layer located on the substrate and under the gate electrode and covering the semiconductor layer, a second inorganic insulating layer located on the first inorganic insulating layer and covering the gate electrode, a third inorganic insulating layer located on the second inorganic insulating layer and including a 1-3th opening in the peripheral area, an organic insulating layer located on the third inorganic insulating layer, covering the source electrode and the drain electrode, and including a second opening overlapping the 1-3th opening in the peripheral area, and a pattern portion located on a layer under the organic insulating layer and overlapping the 1-3th opening and the second opening.

Description

technical field [0001] Embodiments of the present invention relate to a display device, and more particularly, to a display device capable of minimizing defects in a manufacturing process or a use process after manufacturing. Background technique [0002] Among display devices, organic light-emitting display devices are attracting attention as next-generation display devices due to their advantages of wide viewing angle, excellent contrast ratio, and fast response speed. Such an organic light emitting display device is used not only as a display portion of a small product such as a mobile phone, but also as a display portion of a large product such as a television. [0003] Specifically, the organic light-emitting display device has an organic light-emitting element including a hole injection electrode and an electron injection electrode and an organic light-emitting layer formed therebetween, and holes injected from the hole injection electrode and electrons injected from t...
