Abstract

Pairs of a TFT and a pixel electrode, the number of which is (m×n), are provided. The TFT has a gate electrode connected to a scanning line, a source electrode connected to a data line, and a drain electrode connected to the pixel electrode. The pixel electrodes are arrayed in a matrix of m rows and n columns. Each of the pixel electrodes on any column is alternately electrically connected to either of two adjacent data lines via the TFT.
