Embodiment Construction

[0030] FIG. 1A is a perspective view of a mask according to a first embodiment of the present invention, and FIG. 1B shows a pattern forming region of the mask. The mask 1 according to the first embodiment of the present invention includes: a supporting frame 100 having a pattern forming region 110; a plurality of pattern forming parts 200 disposed in the pattern forming region 110; and an auxiliary supporting frame 300 disposed in the pattern forming region 110. Between 200 parts are formed.

[0031] The supporting frame 100 has a rectangular shape and is slightly larger than a substrate on which an organic material such as a light emitting material is deposited. The supporting frame 100 surrounds and supports the pattern forming area 110 .

[0032] Generally, the support frame 100 is made of metal with high strength. The support frame 100 and the auxiliary support frame 300 are integrally formed.

[0033] The pattern forming area 110 includes a plurality of pattern formin...

Abstract

The invention discloses a mask for deposition of a low molecule deposition on a substrate for a display device, which comprises: a supporting frame formed with a pattern forming region; a plurality of pattern forming parts formed in the pattern forming region; and an auxiliary supporting frame formed between the pattern forming parts.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 2005-0122749 filed with the Korean Intellectual Property Office on December 13, 2005, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a mask and a method of manufacturing a display device using the mask for depositing low molecular weight material. Background technique [0004] Organic light-emitting diode (OLED) displays, which can be driven at low voltages, are thin and light, and have wide viewing angles and relatively short response times. OLEDs include a plurality of organic layers such as a hole injection layer and a light emitting layer, which can be formed by a deposition method using a shadow mask and a low-molecular-weight material, an inkjet printing method in which an organic material is dropped through a nozzle, a coating method using a laser. cloth method, and so on.
