A display may include flexible substrate, a blocking layer on the flexible substrate, a pixel on the flexible substrate and the blocking layer, and a scan line, a data line, a driving voltage line, and an initialization voltage line connected to the pixel. The pixel may include an organic light emitting diode, a switching transistor connected to the scan line, and a driving transistor to apply a current to the organic light emitting diode. The blocking layer is in an area that overlaps the switching transistor on a plane, and between the switching transistor and the flexible substrate, and receives a voltage through a contact hole that exposes the blocking layer.

Organic light emitting diode display device

An organic light emitting diode display according to an exemplary embodiment includes: a substrate; a first buffer layer on the substrate; a first semiconductor layer on the first buffer layer; a first gate insulating layer on the first semiconductor layer; a first gate electrode and a blocking layer on the first gate insulating layer; a second buffer layer on the first gate electrode; a second semiconductor layer on the second buffer layer; a second gate insulating layer on the second semiconductor layer; and a second gate electrode on the second gate insulating layer.

Organic light emitting diode display

An organic light emitting diode display includes a substrate, an overlap layer on the substrate, a semiconductor layer on the overlap layer, a first gate conductor on the semiconductor layer, a second gate conductor on the first gate conductor, a data conductor on the second gate conductor, a driving transistor on the overlap layer, and an organic light emitting diode connected with the driving transistor. The driving transistor includes, in the semiconductor layer, a first electrode, a second electrode, with a channel therebetween. A gate electrode of the first gate conductor overlaps the channel. The overlap layer overlaps the channel of the driving transistor and at least a portion of the first electrode. A storage line of the second gate conductor receives a driving voltage through a driving voltage line in the data conductor. The overlap layer receives a constant voltage.

A flexible display device including: a display substrate having a display area and a peripheral area surrounding the display area; a plurality of pixels formed in the display area; a passivation layer covering the pixels from the top to protect the pixels; a polarization film layer provided at the top of the passivation layer and of which an edge is extended outside an edge of the passivation layer; and a film wiring made of a flexible material of which one end is connected to the peripheral area.
