Abstract

According to one embodiment, a display device includes first and second subpixels arrayed in a first direction, a rib layer having first and second pixel apertures, and a partition between the subpixels. The partition is split into first and second partitions by a slit extending in a second direction. The first partition includes a lower portion having first and second side surfaces and an upper portion having first and second end portions. The first end portion protrudes from the first side surface. The second end portion does not protrude from the second side surface or protrudes from the second side surface with a protrusion length shorter than a protrusion length of the first end portion from the first side surface.

Dependent claims

A display device, comprising:

a first subpixel and a second subpixel that are arrayed in a first direction;
a rib layer having a first pixel aperture located in the first subpixel and a second pixel aperture located in the second subpixel;
a partition located between the first subpixel and the second subpixel and provided above the rib layer, wherein
the partition is split into a first partition on the first subpixel side and a second partition on the second subpixel side by a slit extending in a second direction intersecting the first direction,
the first partition comprises:
a lower portion having a first side surface on the first subpixel side and a second side surface on the slit side;
and
an upper portion having a first end portion on the first subpixel side and a second end portion on the slit side and provided on the lower portion,
the first end portion protrudes from the first side surface, and
the second end portion does not protrude from the second side surface or protrudes from the second side surface with a protrusion length shorter than a protrusion length of the first end portion from the first side surface.
