Abstract
A display device includes: a plurality of pixel electrodes arranged in the display region of a first substrate; a color filter provided on a second substrate opposing the first substrate and overlapping the pixel electrode; a planarization insulating layer provided on the color filter; a common electrode provided on the planarization insulating layer and having an opening; a spacer arranged between the pixel electrode and the common electrode; and a light-shielding layer provided between the first substrate and the pixel electrode and overlapping the spacer.

A display device comprising:
- a plurality of pixel electrodes arranged in a display region of a first substrate;
- a color filter provided on a second substrate opposing the first substrate and overlapping the pixel electrode;
- a planarization insulating layer provided on the color filter;
- a common electrode provided on the planarization insulating layer and having an opening;
- a first spacer arranged between the pixel electrode and the common electrode and overlapping the opening;
- a first light-shielding layer provided between the first substrate and the pixel electrode and overlapping the first spacer;
- and
- a second spacer arranged between the pixel electrode and the common electrode and not overlapping the opening, wherein
- a first width of the opening is smaller than a second width of the first spacer,
- the first width is a width of the opening in a direction parallel to a main surface of the second substrate in a cross-sectional view,
- the second width is a width of a common electrode side of the first spacer in a direction parallel to a main surface of the second substrate in the cross-sectional view,
- the first spacer has an outer edge that overlaps the common electrode, and
- a number of second spacers per unit area provided in a center of the display region is different from a number of second spacers per unit area provided in a peripheral area of the display region.
