Abstract: A light emitting display device in one example can include a display region having a first display region with subpixels in a stripe manner and a second display region with the subpixels in a delta manner, a first electrode in each of first and second subpixels in the first and second display regions, a bank including a first trench along a boundary of each column line of the display region, a light emitting layer on the first electrode and the bank, a second electrode on the light emitting layer, and a color filter pattern corresponding to each of the first and second subpixels. In the second display region, a dummy subpixel is arranged alternately with the second subpixel along column and row lines. The first and second subpixels in a first column line crossing the first and second display regions display the first color.
