Abstract

Official abstract text for this publication.

An organic light emitting diode display includes a substrate including a display area and a non-display area adjacent the display area, a plurality of organic light emitting diodes at the display area of the substrate, a plurality of thin film transistors at the display area of the substrate, each of the plurality of thin film transistors being connected to a corresponding one of the plurality of organic light emitting diodes, and a first insulating layer covering an active layer of the plurality of thin film transistors, the first insulating layer having a greater number of contact holes at an outer region of the display area than at a central area of the display area.

First claim

Opening claim text (preview).

What is claimed is: 1 . An organic light emitting diode display, comprising: a substrate comprising a display area and a non-display area adjacent the display area; a plurality of organic light emitting diodes at the display area of the substrate; a plurality of thin film transistors at the display area of the substrate, each of the plurality of thin film transistors being connected to a corresponding one of the plurality of organic light emitting diodes; and a first insulating layer covering an active layer of the plurality of thin film transistors, the first insulating layer having a greater number of contact holes at an outer region of the display area than at a central area of the display area. 2 . The organic light emitting diode display of claim 1 , wherein the first insulating layer contacts the active layer. 3 . The organic light emitting diode display of claim 1 , wherein the plurality of thin film transistors comprises a central thin film transistor at a central area of the display area and an outer thin film transistor at an outer region of the display area, and a width of the active layer of the outer thin film transistor is greater than a width of the active layer of the central thin film transistor. 4 . The organic light emitting diode display of claim 1 , wherein the contact holes include at least one dummy contact hole. 5 . The organic light emitting diode display of claim 4 , wherein the dummy contact hole overlaps the active layer. 6 . The organic light emitting diode display of claim 4 , wherein the dummy contact hole does not overlap the active layer. 7 . The organic light emitting diode display of claim 4 , further comprising: a second insulating layer covering the first insulating layer, wherein the second insulating layer is inside of the dummy contact hole. 8 . The organic light emitting diode display of claim 1 , further comprising: a plurality of data lines extending in one direction on the substrate and connected to the plurality of thin film transistors, and a data driver at the non-display area of the substrate and connected to the plurality of data lines, wherein the outer region is adjacent the data driver. 9 . The organic light emitting diode display of claim 1 , wherein the active layer is heat treated in a state in which the active layer is covered with the first insulating layer. 10 . The organic light emitting diode display of claim 1 , wherein the active layer further comprises a channel region, the channel region being bent at least once.
