1. A display device comprising:
a first color filter;
a second color filter arranged side by side with the first color filter in the same layer, and exhibiting a color different from a color exhibited by the first color filter;
a first pixel electrode disposed on an upper layer side of the first color filter, and overlapping the first color filter;
a second pixel electrode disposed on an upper layer side of the second color filter, and overlapping the second color filter;
a common electrode disposed on an upper layer side or a lower layer side of the first pixel electrode and the second pixel electrode, and overlapping the first pixel electrode and the second pixel electrode;
an insulating film interposed between the first pixel electrode and the common electrode and between the second pixel electrode and the common electrode; and
a light blocking portion disposed at a first boundary between the first color filter and the second color filter on the upper layer side of the first color filter and the second color filter,
wherein, among the first pixel electrode, the second pixel electrode, and the common electrode, an electrode located on an upper layer side of the insulating film is an upper layer electrode, and another electrode located on a lower layer side of the insulating film is a lower layer electrode,
an arrangement direction of the first color filter and the second color filter is a first direction,
a portion of the upper layer electrode overlapping the lower layer electrode is provided with a slit extending along a second direction inclined with respect to the first direction,
an inclined portion extending along a third direction inclined toward the same side as the second direction with respect to the first direction is included in an end portion, of outer peripheral end portions of the light blocking portion, adjacent to the slit in the first direction,
a second angle of the inclined portion that is an angle formed by the third direction with respect to the first direction is larger than a first angle that is an angle formed by the second direction with respect to the first direction,
the first color filter includes a plurality of first color filters arranged in the first direction,
the slit includes a plurality of first slits, each overlapping a corresponding first color filter of the plurality of first color filters,
the light blocking portion includes a plurality of light blocking portions arranged in the first direction, and
each first slit of the plurality of first slits is arranged alternately with each light blocking portion of the plurality of light blocking portions in the first direction.
