Abstract

The depositing apparatus of the invention comprises a depositing source used for accepting deposited substances; and a plurality of nozzles arranged on one side of the depositing source in a first direction and used for ejecting the deposited substances to opposite substrates. The depositing source is divided into a central area and peripheral areas at two ends of the central area with the first direction as a standard. The depositing apparatus also comprises nozzle tops arranged on the nozzles of each peripheral area in a detachable mode, allowing the tail end surfaces ejecting the deposited substances to form inclined angles with the surface of the substrates in the first direction and facing the outer side direction of the depositing source. According to the embodiment of the invention, by increasing the incidence angles of the deposited substances to the substrates, the shadow permeated by the deposited substances between deposition masks and substrates can be restrained, deposition remains can be reduced and deposition uniformity and efficiency can be raised, and thereby the high resolution of an organic light emitting display 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...
