Abstract
A display device includes; a first group of bus lines for transmitting a display signal; a second group of bus lines for transmitting a scan signal and a display unit formed at an intersecting point between the first bus line and the second bus line. The first group and the second group of bus lines are formed in a matrix. The display device further includes switching elements which are selectively opened or closed, the switching elements being provided between the bus lines in the first group or in the second group. Accordingly, even when one of the bus lines is broken, a signal can be supplied from the other bus line to the broken bus line through this switching element.
