Abstract:
1. A method for driving a liquid crystal display device including a plurality of pixels arranged in m rows by n columns (m is a natural number of 12 or more and n is a natural number) comprising the steps of: in a period during which a video signal used for controlling transmission of light of a first color is input to a plurality of pixels arranged in a first row to a k-th row (k is a natural number of less than or equal to (m/3)), a video signal used for controlling transmission of light of a second color is input to a plurality of pixels arranged in a (k+1)th row to a 2k-th row, and a video signal used for controlling transmission of light of a third color is input to a plurality of pixels arranged in a (2k+1)th row to an m-th row, inputting the video signal used for controlling transmission of the light of the first color to a plurality of pixels arranged in the first row to a t-th row (t is a natural number of (k/N) (N is a natural number)), inputting the video signal used for controlling transmission of the light of the second color to a plurality of pixels arranged in the (k+1)th row to a (k+t)th row, and inputting the video signal used for controlling transmission of the light of the third color to a plurality of pixels arranged in the (2k+1)th row to a (2k+t)th row; irradiating the plurality of pixels arranged in the first row to the t-th row with the light of the first color, irradiating the plurality of pixels arranged in the (k+1)th row to the (k+t)th row with the light of the second color, and irradiating the plurality of pixels arranged in the (2k+1)th row to the (2k+t)th row with the light of the third color, the light of the first color, the light of the second color, and the light of the third color corresponding to light in a second red wavelength band, light in a first blue wavelength band, and light in a first green wavelength band in a first period; irradiating the plurality of pixels arranged in the first row to the t-th row with the light of the first color, irradiating the plurality of pixels arranged in the (k+1)th row to the (k+t)th row with the light of the second color, and irradiating the plurality of pixels arranged in the (2k+1)th row to the (2k+t)th row with the light of the third color, the light of the first color, the light of the second color, and the light of the third color corresponding to light in a second green wavelength band, light in a second red wavelength band, and light in a first blue wavelength band in a second period subsequent to the first period, wherein the light of the first color, the light of the second color and the light of the third color are irradiated concurrently with each other, and wherein the light in the first blue wavelength band has a shorter wavelength than the light in the second blue wavelength, the light in the first green wavelength band has a shorter wavelength than the light in the second green wavelength, and the light in the first red wavelength band has a shorter wavelength than the light in the second red wavelength.
