Abstract:
1. A display apparatus, comprising: a plurality of pixel circuits arrayed in a matrix; a plurality of driving wiring lines to which said pixel circuits are connected; and a plurality of signal lines wired so as to cross with said plurality of driving wiring lines and having said pixel circuits connected; said plurality of signal lines being wired in parallel to each other, wherein said plurality of signal lines include a main signal line and a sub signal line wired vertically in parallel to each other and both the main signal line and the sub signal line are disposed on one side of a column of each of said plurality of pixel circuits, and the main signal line and the sub signal line are connected to each other by connecting wiring lines horizontally in parallel to each other, including at a first predetermined position where the sub signal line and one of the connecting wiring lines meet and a second predetermined position where the sub signal line and another one of the connecting wiring lines meet, wherein, where one of said pixel circuits which is to be connected is defective, the main signal line is cut at a predetermined portion between a first position and the defect position and at another predetermined portion between a second position and the defect position, whereby the main signal line between the first and second positions is replaced with the sub signal line.
