Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a display device with which it is possible to improve both manufacturing yield and reliability. This display device (1) comprises: a plurality of pixels (2), each of which includes a light-emitting element (3) and a pixel circuit (4) for driving the light-emitting element (3); and a redundant light-emitting element (5) that, if a light-emitting element (3) fails to be lighted, lights up in lieu of the light-emitting element (3) that fails to be lighted. The plurality of light-emitting elements (3) include a first light-emitting element (31) and a second light-emitting element (32), and the plurality of pixel circuits (4) include a first pixel circuit (41) and a second pixel circuit (42). The plurality of pixels (2) include a first pixel (21) that includes the first light-emitting element (31) and the first pixel circuit (41), and a second pixel (22) that is adjacent to the first pixel (21) and includes the second light-emitting element (32) and the second pixel circuit (42). The redundant light-emitting element (5) is connected to the first pixel circuit (41) and the second pixel circuit (42).
