Abstract

The invention discloses a flexible display device. The flexible display device comprises an active layer; a source electrode disposed on the active layer and connected to the active layer through a first contact hole; a drain electrode disposed in the same layer as the source electrode at a distance from the source electrode in the first direction, the drain electrode being connected to the active layer through a second contact hole; a first pixel electrode disposed on the drain electrode and including a lower surface in contact with an upper surface of the drain electrode and electrically connected to the drain electrode; and a via insulating layer disposed between the source electrode and the first pixel electrode, the drain electrode penetrating the via insulating layer and being electrically connected to the first pixel electrode.

Description

technical field [0001] The present invention relates to a flexible display device, in more detail, to a flexible display device with improved luminous efficiency. Background technique [0002] Recently, flexible display devices are used in various electronic devices such as smartphones, tablet PCs, notebook PCs, and home appliances. Thus, research for improving the luminous efficiency of the flexible display device is ongoing. [0003] The flexible display device may include a transistor, an insulating layer disposed on the transistor, and a light emitting element connected to the transistor. In order to connect the transistor and the light emitting element, a contact hole connecting the drain electrode of the transistor and the anode electrode of the light emitting element needs to be formed. The contact hole may be formed by etching the insulating layer. At this time, the flatness of the upper surface of the insulating layer may be reduced by etching. As a result, the ...
