Patent ID: 8564629

Claim:
A liquid crystal display device comprising: a plurality of pixels arranged in a matrix of m rows by n columns (m and n are natural numbers greater than or equal to 2); 1st to m-th scan lines which are electrically connected to respective n pixels in their respective rows; 1st to n-th signal lines which are electrically connected to respective m pixels in their respective columns; a scan line driver circuit which is electrically connected to the 1st to m-th scan lines; and a signal line driver circuit which is electrically connected to the 1st to n-th signal lines, wherein the scan line driver circuit includes 1st to m-th pulse output circuits which shift a shift pulse sequentially per shift period in response to a start pulse, wherein an A-th pulse output circuit (A is a natural number less than or equal to m/2) comprises a 1st output terminal for outputting a shift pulse to an (A+1)-th pulse output circuit during an A-th shift period and a 2nd output terminal for outputting a selection signal to an A-th scan line in an A-th scan line selection period which overlaps with the A-th shift period, wherein an (A+B)-th pulse output circuit (8 is a natural number less than or equal to m/2) comprises a 1st output terminal for outputting a shift pulse to an (A+B+1)-th pulse output circuit during the A-th shift period and a 2nd output terminal for outputting a selection signal to an (A+B)-th scan line in an (A+B)-th scan line selection period which overlaps with the A-th shift period, wherein the signal line driver circuit supplies a pixel image signal for an A-th row to the 1st to n-th signal lines in a first period which overlaps with the A-th scan line selection period, wherein the signal line driver circuit supplies a pixel image signal for an (A+B)-th row to the 1st to n-th signal lines in a second period which overlaps with the (A+B)-th scan line selection period, and wherein the first period and the second period do not overlap with each other.
