Embodiment approach

[0090] According to an exemplary embodiment of the present disclosure, the first vertical bank 161 has a left protrusion A, and the second vertical bank 162 has a right protrusion B, so that the thickness variation as described above can be reduced, and the organic light is emitted. The thickness of the layers can be reduced. according to image 3 In an exemplary embodiment of the present disclosure shown in , the first vertical bank 161 has a left protrusion A at a position where it overlaps the first horizontal bank 151 and the second horizontal bank 152 , and the second vertical bank The bank 162 has a right protrusion B at a position where it overlaps the first horizontal bank 151 and the second horizontal bank 152 . Therefore, the distance between the first vertical bank 161 and the second vertical bank 162 on the first horizontal bank 151 and the second horizontal bank 152 is extended to be larger than the first vertical bank surrounding the first sub-pixel SP1. 161 an...

Abstract

The present disclosure relates to an organic light emitting display device. According to an aspect of the present disclosure, an organic light emitting display device includes a plurality of sub-pixels including a first sub-pixel, a second sub-pixel and a third sub-pixel, a first electrode, a horizontal bank including a first horizontal bank and a second horizontal bank that are alternately arranged in a first direction to cover edges of the first electrodes, a vertical bank including a first vertical bank, a second vertical bank, and a third vertical bank that are alternately arranged in a second direction to cover edges of the first electrode and disposed on the horizontal bank, an organic light emitting layer and a second electrode. An area wider than the first sub-pixel is formed on the first horizontal bank or the second horizontal bank adjacent to the first sub-pixel, and ink is injected on the area, whereby color mixing of the ink can be minimized. A high-resolution organic light emitting display device can be implemented, simultaneously with improving display quality of the organic light emitting display device.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2019-0179918 filed with the Korean Intellectual Property Office on December 31, 2019, the disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to an organic light emitting display device, and more particularly, to an organic light emitting display device having a color by minimizing color mixing of ink and thickness variation in the organic light emitting layer when the organic light emitting layer is formed through a solution process. Improved display quality. Background technique [0004] Unlike a liquid crystal display device (LCD) having a backlight, an organic light emitting display device (OLED) can be manufactured light and thin by including an organic light emitting element as a self-luminous element, and allows a simple manufacturing process. In addition, organic li...
