Abstract

Provided are an organic light emitting diode display and a manufacturing method thereof. An organic light emitting diode display according to one or more embodiments of the present invention includes: a substrate; a plurality of organic light emitting elements arranged on the substrate and configured to emit light; a touch panel on the plurality of organic light emitting elements; a window on the plurality of organic light emitting elements. on the touch panel; and a first light blocking layer at a surface of the window and having an exposed area corresponding to a path of light emitted from the plurality of organic light emitting elements and exposing a part of the window.

Description

technical field [0001] The present disclosure relates to organic light emitting diode displays and methods of manufacturing the same. Background technique [0002] An organic light-emitting element of an organic light-emitting diode display includes two electrodes and an organic emission layer between the two electrodes, and electrons injected from a cathode serving as one electrode and holes injected from an anode serving as the other electrode pass through the organic emission layer. are combined with each other to generate excitons, and light is emitted by emitting the energy of the excitons. [0003] An organic light emitting diode display includes a plurality of pixels including an organic light emitting element configured by a cathode, an anode, and an organic emission layer, and in each pixel, a plurality of transistors and a storage capacitor for driving the organic light emitting element are formed. The plurality of transistors typically includes switching transist...
