Benefits of technology

[0016] The present invention provides a light emitting element capable of improving luminance and uniformity of the luminance.
[0022] Therefore, ejecting order of the light emitting material is controlled so that evaporation rate of volatile material in the light emitting material is not affected by adjacent light emitting patterns. Therefore, thicknesses of the light emitting patterns are uniformized so that luminance of the display apparatus is improved and uniformized.

Problems solved by technology

When the profiles of the light emitting patterns are different from one another, the OLED apparatus has non-uniform luminance so that an image display quality of the OLED apparatus is deteriorated.

Abstract

In a method of manufacturing a light emitting element, a plurality of first electrodes arranged in a matrix shape is formed on a pixel area of a base substrate. A bank is formed between the first electrodes. A light emitting material is ejected on a portion of the first electrodes spaced apart from one another to form a plurality of first light emitting patterns. The light emitting material is erected on a portion of the first electrodes between the first light emitting patterns to form a plurality of second light emitting patterns. A second electrode is formed on the first and second light emitting patterns. Therefore, a luminance of the light emitting element is improved and uniformized.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a Divisional of U.S. application Ser. No. 11 / 017,532 filed on Dec. 20, 2004, which claims priority to Korean Application No. 2003-93741 filed on Dec. 19, 2003, the disclosure of which is hereby incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1.
