Patent ID: 7199775

Claim:
A display device array substrate, comprising: a plurality of scanning lines running in a row direction on a substrate; a plurality of signal lines running in a column direction on the substrate; and a display unit having m pixel columns in each of which n rows of pixels are arranged, wherein each pixel includes a switching element placed at an intersection of each scanning line and each signal line, and one switching element is connected per row to each signal line, a switching element in an Nth row of an Mth pixel column and a switching element in an (N+1)th row of an (M+1)th pixel column are connected to the same signal line, and video signals having opposite polarities are supplied to adjacent signal lines, wherein the display unit includes a first pixel column placed between first and second signal lines, and an mth pixel column placed between an mth signal line and an auxiliary signal line electrically connected to the first signal line, switching elements in the first and mth pixel columns of the Nth row are connected to the second signal line and auxiliary signal line, respectively, and switching elements in the first and mth pixel lines of the (N+1)th row are connected to the first and mth signal lines, respectively, wherein each of N, and M is an integer of 1 or more, and each of n, m is an integer of 2 or more.
