Repair method of a slit nozzle for display panel coating and the slit nozzle for display panel coating

摘要

The present invention provides a display panel coating slit nozzle repair method and a display panel coating slit nozzle including a body (110) that is formed to be elongated in the width direction of a display panel and is divided into one side and the opposite side which are coupled in close contact with each other and ribs (115) that protrude from respective lower surfaces (113) of the body (110) and are formed to be separated from each other, in which the ribs (115) are formed to be inclined toward an outer lateral side as an outer side surface (117) goes up and have lower ends (118) formed to be pointed. A primary coating layer (120) and a secondary coating layer (140) are formed in the outer side surface (117) and an inner side surface (119) of the rib (115) and cut so that a secondary coating layer (140) is configured in the inner side surface (119) of the rib (115) and the secondary coating layer (140) is supported by the primary coating layer (120). Accordingly, the body (110) can be repaired without being replaced in a case where the rib (115) is impaired. In addition, the display panel coating slit nozzle (100) according to the present invention is configured so that the secondary coating layer (140) is configured in the inner side surface of the rib (115) and the primary coating layer (120) supports the secondary coating layer (140). Accordingly, scratching in the rib (115) by the secondary coating layer (140) can be prevented.
