Abstract: A display device comprises a substrate; a circuit array layer comprising pixel drivers, data lines, first dummy lines, and second dummy lines; and a light emitting array layer. The display area comprises middle, first side, and second side regions. The data lines comprise first, second, and third data lines disposed in the middle, first side, and second side regions, respectively. The first dummy lines comprise a first data detour line disposed in the first side region and adjacent to a part of the second data line, and auxiliary lines. The second dummy lines comprise a second data detour line configured to connect the first data detour line to the third data line, and additional lines. The auxiliary lines comprise a bias auxiliary line to which a bias power is applied; and a second power auxiliary line to which a second power is applied.

Abstract: In an organic light emitting display device which displays an image in a first mode or a second mode, the organic light emitting display device includes: a first scan driver which supplies a first scan signal having a first voltage to first scan lines; a second scan driver which supplies a second scan signal having a second voltage larger than the first voltage to second scan lines; and a pixel unit including pixels each coupled to a corresponding first scan line and a corresponding second scan line. When a first image displayed in the second mode is changed to a second image to be displayed in the second mode, the second image is displayed in the first mode during a predetermined portion of a period, in which the second image is displayed, and is displayed in the second mode during the remaining portion of the period.
