US 2014/0272322 A1 · COATING DEVICE, METHOD OF MANUFACTURING DISPLAY SUBSTRATE USING THE SAME AND DISPLAY SUBSTRATE MANUFACTURED USING THE SAME

Abstract

A coating device includes an upper stage, a lower stage and a spraying part. The upper stage masks an upper surface of a display panel. The lower stage masks a lower surface of the display panel. The spraying part sprays ink to a side surface of the display panel. The side surface of the display panel is exposed between the upper stage and the lower stage. The coating device includes the upper stage and the lower stage, so that the coating device may form a coating layer of uniform thickness by precisely spraying ink. In addition, a cross-section of the coating layer may be precisely formed having specific shape such as an L or C shape. A display apparatus having high light usage efficiency and reduced light leakage may be provided by using the coating device.
