Array substrate and in-plane switching liquid crystal display panel

An in-plane switching (IPS) liquid crystal display panel, comprising:

• an array substrate, comprising:
• a first substrate;
• a plurality of data lines, disposed on the first substrate;
• a plurality of gate lines, disposed on the first substrate, wherein at least one pixel region is defined by the data lines and the gate lines crossing with one another;
• at least one pixel electrode, disposed on the first substrate and at least partially located in the pixel region, wherein the pixel electrode comprises at least one first branch electrode;
• at least one common electrode, disposed on the first substrate and at least partially located in the pixel region, wherein the common electrode comprises at least one second branch electrode, and the first branch electrode and the second branch electrode are disposed alternately in a first direction;
• at least one light-shielding pattern, disposed on the first substrate and at least partially located in the pixel region, wherein the light-shielding pattern is disposed between a first data line adjacent to the pixel region and the first branch electrode in the first direction;
• and
• at least one auxiliary electrode, disposed on the first substrate and at least partially located in the pixel region, wherein the auxiliary electrode is at least partially located between the first branch electrode and the light-shielding pattern in the first direction, and the auxiliary electrode is electrically connected to the pixel electrode;
• an opposite substrate, disposed opposite the array substrate;
• and
• a liquid crystal layer, disposed between the array substrate and the opposite substrate.
