Abstract: A panel defect detection method and an organic light emitting display device. A region having a high probability of a panel defect is intensively sensed through panel defect detection based on sensing results of characteristic values according to subpixels on sensing subpixel lines in an amount equal to the number of sensing subpixel lines preset in specific regions rather than all regions of a display panel. Rates and accuracy in detection of panel defects can be improved.

Abstract: Embodiments of the present disclosure are related to a display device, as a voltage line connection pattern electrically connecting a voltage line and a circuit element in a subpixel includes a first voltage line connection pattern, for example, disposed using an active layer and a second voltage line connection pattern, for example, disposed using a metal layer and not disposed in a part area on the first voltage line connection pattern, a damage of an electrode located at a periphery can be prevented or at least reduced when cutting by a laser for a repair. Furthermore, as the voltage line connection pattern which is easily cut and has a low resistance is disposed, a structure can be provided that is capable of responding to various types of repairs such as a disconnection defect of other signal lines.
