Array substrate, liquid crystal display panel and liquid crystal display device

A liquid crystal display panel, comprising a color filter substrate, a liquid crystal layer and an array substrate, the array substrate comprises a first substrate and a data line, the data line being arranged on the first substrate;

• a spacer protruding from the first substrate and having a vertical projection on the first substrate not intersecting with the data line;
• a light-shielding electrode located on a side of the data line away from the first substrate, wherein the light-shielding electrode comprises a main section and a protruding section which are integrated with each other, a vertical projection of the main section on the first substrate covers the data line, the protruding section is stacked on the spacer, and the protruding section contacts the color filter substrate, the color filter substrate is arranged opposite to the array substrate, the protruding section contacts the color filter substrate, the liquid crystal layer is located between the color filter substrate and the array substrate and changes liquid crystal molecules of the liquid crystal layer according to a pressure difference between the color filter substrate and the array substrate.
