<p>An active-matrix-type liquid crystal display device supplies signal potentials to signal lines of a liquid crystal display panel (14) according to a time-division drive method using time-division switches (30-I, 30-k). The low-level potential of select pulses to be supplied from a select pulse generating circuit (36) to CMOS analog switches (31, 32, 33) of the time-division switches (30-I, 30-k) is set to be lower than the low-level potential of a signal potential outputted from a horizontal drive circuit (22). With this arrangement, even if the signal potential of a non-selected signal line is decreased due to the crosstalk of a signal potential from a selected signal line to the non-selected signal line, the generation of insufficient contrast and non-uniformity of the luminance in the horizontal direction can be prevented. As a consequence, a high image quality is maintained. <IMAGE></p> |
