PROBLEM TO BE SOLVED: To prevent flickering in an image to be displayed on a display panel while suppressing an increase in power consumption, a heat value and manufacturing costs.SOLUTION: When a source driver is divided into a plurality of IC chips 22to 22, a reference gradation voltage based on first gamma characteristics generated by the first IC chip 22is output, and supplied to each of the first and second IC chips 22and 22. Furthermore, a reference gradation voltage based on second gamma characteristics generated by the second IC chip 22is output, and supplied to each of the first and second IC chips. In each IC chip, a first gradation voltage is generated on the basis of the reference gradation voltage of the first gamma characteristics input from the outside, and a second gradation voltage is generated on the basis of the reference gradation voltage of the second gamma characteristics input from the outside. The reference gradation voltage generated and output for each IC chip is supplied to each of those IC chips via a reference gradation voltage supply line 12 print-wired on a substrate in a state where it is extended in a screen horizontal direction of a display panel. |
