Abstract:
1. A thin film transistor (TFT) array substrate, comprising: a substrate having a device region and a cutting mark region; a plurality of pixel structures disposed in the device region, each pixel structure comprising a TFT, a pixel electrode and a passivation layer covering the TFT; and a plurality of cutting marks disposed in the cutting mark region, the cutting marks being symmetrically disposed at two sides of a predetermined cutting position and all of the cutting marks being connected to one another so as to arrange into a straight line perpendicular to a predetermined cutting direction, wherein the adjacent cutting marks are connected to each other but are not overlapped to each other, and the cutting marks are constituted of at least two colors, at least two shapes, at least one color and at least one shape, or a combination thereof, wherein each of the cutting marks has a width perpendicular to the predetermined cutting direction, and the widths of all of the cutting marks are the same such that the distance between each cutting mark and the predetermined cutting position is a multiple of a constant.
