By forming a repair structure in a horizontal direction and vertical direction by using one or more repair lines between two or more pixels adjacent to each other in a display panel, even though a dark spot appears due to a defective operation of one pixel, the one pixel may be compensated to be driven by using the other pixel.

Organic light emitting display device and repair method thereof

An organic light emitting display device and a method of repairing the device are discussed. According to an embodiment, the device includes a display panel having pixels, each including an OLED in every pixel area defined as scan and data lines intersect with each other and having a repair structure in at least one of horizontal and vertical directions between adjacent pixels by one or more repair lines; a timing controller configured to generate compensation data when a dark spot is generated in one of the plurality of pixels of the display panel, and adjust a magnitude of image data according to the compensation data; and a data driver configured to adjust a magnitude of a data voltage according to the image data adjusted in magnitude, and output the data voltage adjusted in magnitude to the data lines.

Discussed is an organic light emitting display device that may include a first pixel on a substrate; a switching transistor with a first active layer provided inside the first pixel; a driving transistor with a second active layer provided inside the first pixel; a first light shielding layer overlapping the second active layer; and a second light shielding layer overlapping the first active layer, wherein the first light shielding layer is connected with the driving transistor, and the second light shielding layer is electrically insulated from the first light shielding layer.
