1. A liquid crystal display device comprising:
a first substrate;
a second substrate arranged facing the first substrate;
a liquid crystal layer interposed between the first substrate and the second substrate;
a seal which is arranged between the first substrate and the second substrate so as to surround the liquid crystal layer, the seal having a curved indent in an outer peripheral shape thereof; and
first spacers which are provided on a surface of the first substrate facing the liquid crystal layer and maintain an interval between the first substrate and the second substrate,
characterized in that, when: a region corresponding to the liquid crystal layer for displaying an image constitutes a first region,
a region corresponding to the liquid crystal layer and surrounded by the curved indent of the seal, the outer periphery of the first region, a first normal line extending downward from a start point of the curved indent of the seal to the outer periphery of the first region, and a second normal line extending downward from an end point of the curved indent of the seal to the outer periphery of the first region constitutes a second region, and
a region corresponding to the liquid crystal layer other than the first region and other than the second region constitutes a third region,
in a plan view, a surface area occupied by the first spacers per unit surface area of the second region is greater than a surface area occupied by the first spacers per unit surface area of the third region.
