摘要

A display device according to the present disclosure includes: a drive circuit array substrate including drive circuits arranged in an array pattern on a semiconductor substrate; and light emitting elements arranged in an array pattern over the drive circuits and driven by the drive circuits, in which in a drive circuit group including a plurality of the drive circuits that are adjacent to each other, a well tap is provided in a part of the drive circuits of the plurality of the drive circuits included in the drive circuit group.

說明書

FIG. 17 is a schematic partial plan view of a substrate and the like for explaining a circuit arrangement in a drive circuit array substrate according to the first modification.

In the first embodiment, it has been described with reference to FIG. 7 that the second drive circuit belonging to one drive circuit group of the pair of the drive circuit groups has a circuit arrangement in which the second drive circuit belonging to the other drive circuit group is vertically and horizontally inverted. On the other hand, in the first modification, a second drive circuit belonging to one drive circuit group of the pair of the drive circuit groups has a circuit arrangement in which a second drive circuit belonging to the other drive circuit group is horizontally inverted.

Subsequently, a transition from the arrangement of the drive circuits of the reference example to the arrangement of the drive circuits of the first modification will be described with reference to FIGS. 18A to 19B.

FIG. 18A illustrates a state after the processes illustrated in FIGS. 8A, 8B, and 9A are performed. Room generated by the omission of the well taps WTP of the respective drive circuits is denoted by a reference sign Room.
