Abstract
An LCD panel including a first substrate, multiple horizontal and vertical conductive lines, support pads to form first protrusions, a second substrate, a main spacer, a compensation spacer, and a liquid crystal layer is provided. The main spacer and the compensation spacer are in sliding contact with the first protrusions in the horizontal or vertical direction in a plane of the LCD panel, and the compensation spacer is disposed around the main spacer and corresponding first protrusions are next to the compensation spacer. In the horizontal or vertical direction, the main spacer is partially contacted with the first protrusion to obtain a reduced contacting area, and the compensation spacer is partially contacted with the adjacent first protrusion to obtain an increased contacting area. The reduced contacting area between the main spacer and the first protrusion is equal to the increased contacting area between the compensation spacer and the first protrusion.
