Embodiment Construction

[0024] The present invention will be described more fully below with reference to the accompanying drawings, in which the preferred embodiments of the present invention are shown. However, the present invention may be implemented in different forms and should not be construed as being limited by the illustrated embodiments. The same reference numerals indicate the same elements throughout the specification.

[0025] figure 2 It is a cross-sectional view of the OLED according to the present invention.

[0026] Reference figure 2 , A predetermined element is formed on the substrate 110, and the first electrode 220 is patterned and formed on the substrate 110. The substrate 110 may use a transparent insulating substrate, such as glass, plastic, and quartz.

[0027] When the first electrode 220 is an anode, the first electrode may be a transparent electrode made of ITO or IZO with a high work function, or a reflective electrode with a reflective layer as a lower layer, and the refl...

Abstract

An organic light emitting display and method of fabricating the same are provided. The OLED and method of fabricating the same is capable of forming an inorganic pixel defining layer having an opening for exposing at least a portion of the first electrode and making the inorganic pixel defining layer have a curved top surface without breakpoints. Since the top surface of the inorganic pixel defining layer has the curved cross-section without breakpoints, the first electrode and the organic layer pattern are closely adhered during a laser induced thermal imaging process to enable the transfer using a laser beam having low energy, thereby improving transfer efficiency, improving luminous efficiency of the OLED, and increasing lifetime of the OLED.

Description

[0001] Cross references to related applications [0002] This application claims the priority and rights of Korean Patent Application No. 2004-0075643 filed on September 21, 2004, the disclosure of which is hereby incorporated by reference in its entirety. Technical field [0003] The present invention relates to an organic light emitting display and a method of manufacturing the display, and more particularly to an organic light emitting display including an inorganic pixel defining layer with a curved top surface without breakpoints, and a method of manufacturing the display. Background technique [0004] Since the organic light emitting display (OLED) in the flat panel display is an emissive display, in which the organic compound is electrically excited to emit light, unlike the liquid crystal display (LCD), it does not require a backlight unit, thereby making it possible to manufacture a thin and light OLED and simplify the process . In addition, since OLEDs can be manufacture...
