Abstract: A liquid crystal display panel and a fan-out area thereof are provided. The fan-out area is arranged in a peripheral circuit area of the liquid crystal display panel and includes a middle wire and multiple fan-out wires arranged at two sides thereof. The middle wire and the fan-out wires each are disposed with at least one first wire pattern. Along each of directions toward the middle wire, widths of the first wire patterns of different wires are successively increased and/or lengths of the first wire patterns are successively decreased. The first wire patterns of a same wire have same width and length. Accordingly, the present invention can reduce the resistance differences among the wires in the fan-out area, color washout and non-uniform brightness caused by the resistance differences can be relieved or avoided, and is beneficial to the narrow border design of the liquid crystal display panel.

Abstract: The present invention proposes a TFT array substrate includes: a substrate; scan lines on the substrate; data lines intercrossing with the scan lines; a first insulating layer between the scan lines and the data lines; a second insulating layer on the first insulating layer and covering the data lines; a common electrode layer on the second insulating layer, comprising first holes located above the data lines. The first holes uncover the second insulating layer. The present invention decreases parasitic capacitance between the common electrode layer and data lines and between the common electrode layer and scan lines by decreasing overlaping sections between a common electrode layer and the data lines and between the common electrode layer and the scan lines. Therefore load of the data lines and the scan lines decreases, charge efficiency of the pixels increases, and display effect of an LCD panel is therefore improved.
