Deposition device and method of manufacturing organic light-emitting display device using same

Abstract

The deposition device according to the present invention includes: a deposition source for containing deposition materials; and a plurality of nozzles arranged on one side of the deposition source along a first direction and used for spraying the deposition materials onto an opposite substrate. The deposition source is divided into a central area and peripheral areas at two ends of the central area based on the first direction. The deposition device further includes: detachably formed on the nozzles arranged on the respective peripheral regions, and such that an end surface for spraying the deposition substance is formed to form an inclination with the substrate surface along the first direction Angle and the top of the nozzle toward the outside of the deposition source. According to the embodiments of the present invention, by increasing the incident angle of the deposition material incident on the substrate, the shadow phenomenon of the deposition material penetrating into the deposition mask and the substrate can be suppressed, the deposition margin can be reduced, and the deposition uniformity and deposition efficiency can be improved. Thereby, high resolution of the organic light emitting display device can be easily realized.

Description

technical field [0001] The present invention relates to a deposition device and a method for manufacturing an organic light-emitting display device using the same, in particular to a deposition device capable of preventing shadowing by controlling the angle at which a deposition material is sprayed, and a method for manufacturing an organic light-emitting display device. Background technique [0002] Among display devices, organic light-emitting display devices not only have the advantages of wide viewing angle and excellent contrast ratio, but also have advantages such as fast response speed, and thus are attracting attention as next-generation display devices. [0003] Generally, in order to realize colors by recombining holes and electrons injected from the anode and cathode in the light emitting layer to emit light, the organic light emitting display device has a stacked structure in which the light emitting layer is inserted between the anode and the cathode. However, i...
