Embodiment Construction

[0029] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0030] The drawings and description are to be regarded as illustrative in nature and not restrictive. In addition, for better understanding and ease of description, in the drawings, the size and thickness of each element is a random sample, and the present invention is not limited thereto. In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In contrast, when...

Abstract

An organic light emitting diode (OLED) display including a substrate (100), a thin film transistor (TFT) (20) formed on the substrate (100), an OLED (70), a colored polarizing member (300) on the OLED, and a colored material (200) on the OLED and having a color that is different from that of the polarizing member (300). The OLED includes a pixel electrode (710), an organic emission layer (720) onthe pixel electrode (710), and a common electrode (730) on the organic emission layer (720), wherein the pixel electrode (710) is coupled to the TFT (20).

Description

technical field [0001] The present invention relates to an organic light emitting diode (OLED) display. Background technique [0002] An OLED display includes a plurality of OLEDs having a hole injection electrode, an organic emissive layer, and an electron injection electrode. By emitting light with energy generated when excitons (ie, electron-hole pairs) combine to drop from an excited state to a ground state, the OLED display displays images using the emitted light. [0003] Therefore, the OLED display has a self-luminous characteristic, and compared with a liquid crystal display (LCD), since the OLED display does not require a separate light source, its thickness and weight can be reduced. In addition, OLED displays are suitable for use in mobile electronic devices because they have high-quality characteristics, such as low power consumption, high brightness, and high response speed. [0004] Typically, electrodes and other metal wiring of OLED displays are capable of ...
