Abstract: A foldable display device includes a display panel including a folding area and non-folding areas on both sides of the folding area in a folding direction; a first support substrate configured to support the display panel under the display panel and including a plurality of opening patterns corresponding to the folding area; and a second support substrate between the display panel and the first support substrate and including a plurality of protrusion patterns protruding to be inserted into the plurality of opening patterns. Sizes of the plurality of protrusion patterns are smaller than sizes of the corresponding plurality of opening patterns. Therefore, it is possible to improve durability and prevent or at least reduce degradation of folding characteristics of the foldable display device.

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. Wherein 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. And, a high-resolution organic light emitting display device can be implemented, simultaneously with improving display quality of the organic light emitting display device.
