A display device may comprise: a first electrode; a second electrode; a light emitting element; a first pattern portion arranged adjacent to a first area where the first electrode and the light emitting element overlap on a plane; a second pattern portion arranged adjacent to a second area where the second electrode and the light emitting element overlap on a plane; a first connection electrode covering the light emitting element and the first pattern portion, and electrically connected to the light emitting element and the first electrode; and a second connection electrode covering the lightemitting element and the second pattern portion, and electrically connected to the light emitting element and the second electrode.
Description
technical field [0001] The present invention relates to a display device with improved reliability and a method for manufacturing the display device. Background technique [0002] The display device may include a light emitting element. The light emitting element may be electrically connected to the electrodes, and may emit light according to a voltage applied to the electrodes. A light emitting element may be directly formed on the electrode. Alternatively, the light emitting element may be formed separately, and then may be disposed on the electrode. When a separately formed light emitting element is provided on an electrode, connection between the light emitting element and the electrode may not be easy depending on the shape of the light emitting element. In addition, cracks generated in connection electrodes for connecting the light emitting element and the electrodes cause a phenomenon in which resistance between the light emitting element and the electrodes increas...
