Abstract: A display apparatus has a plurality unit pixels each divided into a least three sub-pixels for displaying a halftone. The at least three sub-pixels have mutually different areas, so that one sub-pixel among the at least three sub-pixels has a maximum area which does not exceed a total area of the remaining sub-pixels. As a result, it is possible to obviate a so-called linear defect occurring in a multi-level gradational display by suppressing the shift of gravity center of light spots and change in sub-pixel arrangement pattern in displaying slightly different gradation levels.

The control means switches a driving waveform based on data from the temperature detection device. The effective value of a selection pulse is preferable changed simultaneously with the waveform switching. The waveform switching may be performed in during a temperature rise rather then during a temperature fall, and may be forbidden for a prescribed period after a waveform switching. The waveform switching may be also be performed between two types of waveforms including or not including a pause period.
