Abstract
Provided is a liquid crystal display panel which allows high quality display by suppressing a disturbance of liquid crystal molecule alignment caused by formation of liquid crystal alignment control protrusions. The liquid crystal display panel of the present invention is a liquid crystal display panel including a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, one of the pair of the substrates including a colored layer, a light-shielding layer, and walled liquid crystal alignment control protrusions projecting toward the other substrate, the liquid crystal alignment control protrusions including a main protrusion and a secondary protrusion lower than the main protrusion, the secondary protrusion being provided on the colored layer along a borderline between the colored layer and the light-shielding layer, and the total of the height of the secondary protrusion and that of the colored layer being substantially the same as the height of the light-shielding layer.
