PROBLEM TO BE SOLVED: To provide a driver circuit which, even when a voltage drop occurs in a gradation voltage line, makes possible to restore the voltage early and output the gradation voltage stably.SOLUTION: The driver circuit has: a gradation voltage generation circuit 41 for generating m pieces of gradation voltages indicating m gradation levels (m is an integer equal to or greater than 2); n pieces of decoder circuits 42 for selecting each of n pieces of drive voltages corresponding to n data from the m pieces of gradation voltages on the basis of the inputted n pieces of gradation signals (n is an integer equal to or greater than 2) and outputting the selected drive voltage; m gradation voltage lines Wx, each transmitting each of the m gradation voltages to each of the n pieces of decoder circuits; and an electric charge replenishment circuit 43 which, when a voltage drop occurs in one of the m pieces of gradation voltage lines, replenishes the gradation voltage line in which the voltage drop occurred with an electric charge.SELECTED DRAWING: Figure 3 |
