In a liquid crystal display panel, a gap between an array substrate 2a and an opposing substrate 3 is made constant by using spacers 23 mixed in a seal agent 22 provided around a display area A. A bottom-up pattern 17 formed in the same layer as that of a light shield 16 is formed in a seal area B and a leveling layer 19 on the seal area B is made thinner in order to minimize an amount of sink of the spacers 23 into the leveling layer 19 thereby make the gap between the substrates uniform.
