Abstract

A display apparatus, comprises a plurality of pixels arranged in pluralities of rows and columns. A plurality of first control lines is provided, each connecting a column of pixels in common, and a plurality of second control lines is provided, each connecting a row of pixels in common. The first control lines are divided into a plurality of blocks. Third control lines are disposed so that the first control lines in each of the blocks are commonly connected by a third control line. A multiplexing switching element is disposed at each connection between the third control lines and the first control lines. Further, a difference in output voltage between two multiplexing switching elements disposed at a boundary between a neighboring pair of blocks is 50 mV or less.
