Abstract

A method of manufacturing a display includes selecting at least one of pixels which can be seen as a luminous line or a luminous dot with a dark line-like tail when an inspection image is displayed, and breaking a first conductive path connecting a display element to a power supply terminal and a second conductive path connecting the first conductive path to a video signal line in the selected pixel.

Claims (8)

1. A method of manufacturing a display comprising an insulating substrate, pixels arranged in a matrix form on the insulating substrate, and video signal lines arranged correspondently with columns which the pixels form, wherein each of the pixels comprises a drive control element which includes a control terminal, a first terminal connected to a first power supply terminal, and a second terminal outputting a current with a magnitude corresponding to a voltage between the control terminal and the first terminal, a display element which includes a first electrode, a second electrode connected to a second power supply terminal, and an active layer interposed between the first and second electrodes, an output control switch which is connected between the second terminal and the first electrode, a switch group which switches an electrical connection between first and second states, the first state being a state that the second terminal, the video signal line, and the control terminal are electrically connected to one another, and the second state being a state that the second terminal, the video signal line, and the control terminal are electrically disconnected from one another, and a capacitor which is connected to the control terminal, comprising:

selecting at least one of the pixels which can be seen as a luminous line or a luminous dot with a dark line-like tail when an inspection image is displayed; and

breaking a first conductive path electrically connecting the first electrode to the first power supply terminal and a second conductive path electrically connecting the second terminal to the video signal line in the selected pixel.

2. The method according to claim 1 , wherein breaking the first and second conductive paths includes irradiating the first and second conductive paths with a laser beam.

3. The method according to claim 1 , wherein the first and second conductive paths include first and second polysilicon portions, respectively, and

wherein breaking the first and second conductive paths includes breaking the first and second polysilicon portions.

4. The method according to claim 3 , wherein breaking the first and second conductive paths includes irradiating the first and second polysilicon portions with a laser beam.

5. The method according to claim 1 , wherein the display element is an organic EL element.
