Abstract

A display device includes a substrate, a sub-pixel structure, a light blocking member, and a reflective member. A display area including a sub-pixel area is defined on the substrate. The sub-pixel structure is disposed in the sub-pixel area on the substrate. The light blocking member is disposed over the sub-pixel structure, and a first opening is defined in a portion of the light blocking member which overlaps the sub-pixel structure. The reflective member is disposed between the light blocking member and the sub-pixel structure, and the reflective member surrounds the sub-pixel structure and the first opening.

Dependent claims

A display device comprising:

a substrate on which a display area including a sub-pixel area is defined;
a sub-pixel structure disposed in the sub-pixel area on the substrate;
a light blocking member disposed over the sub-pixel structure, wherein a first opening is defined in a portion of the light blocking member which overlaps the sub-pixel structure;
and
a reflective member disposed between the light blocking member and the sub-pixel structure, wherein the reflective member surrounds the sub-pixel structure and the first opening, and a sidewall defining a major surface plane of the reflective member is orthogonal to a top surface defining the substrate.
