Abrégé
(EN)
Provided is a liquid crystal display panel, comprising a second substrate structure, the second substrate structure at least comprising several sub-pixel areas (SP), a first substrate structure at least comprising: a first substrate (111), a common electrode layer (114), an insulating layer (115), several auxiliary spacers (116b), a first conductive film layer (117) and a first alignment film layer (118), the common electrode layer (114), the insulating layer (115) and the several auxiliary spacers (116b) being sequentially arranged on the first substrate (111), the auxiliary spacers (116b) being located above the corresponding sub-pixel areas (SP) and at an interval from the second substrate structure, the first conductive film layer (117) being arranged on the insulating layer (115) and covering the auxiliary spacers (116b), the first alignment film layer (118) covering the insulating layer (115), except the area covered by the first conductive film layer (117), and the first conductive film layer (117), except above the auxiliary spacers (116b). The use of the auxiliary spacers (116b) implements a more uniform orientation of liquid crystal molecules, thereby simplifying a manufacturing process and saving costs.
