Abstract

A display apparatus includes a display panel including a plurality of pixels, and a cover panel including a window layer, an optical filter layer, a color filter layer and a bezel layer. The window layer includes a transmission region and a bezel region adjacent to the transmission region. The optical filter layer is disposed on the transmission region of the rear surface of the window layer. The color filter layer is disposed on the optical filter layer and includes a quantum dot. The bezel layer is disposed on the bezel region of the rear surface. The optical filter layer includes a partition wall layer, in which an opening is defined, a light-blocking layer disposed on the partition wall layer, and a reflection layer disposed in the opening. The bezel layer has a same color as the light-blocking layer.

Claims (10)

1. A method of fabricating a display apparatus, the method comprising:

forming a partition wall layer, in which a plurality of openings are defined, on a transmission region of a window layer, wherein the window layer is divided into a bezel region adjacent to the transmission region;

forming a light-blocking layer by forming and patterning a first material on the partition wall layer;

forming a bezel layer by forming and patterning a second material on the bezel region of the window layer;

forming reflection patterns, which have different colors from each other, in corresponding ones of the openings;

forming an optical filter layer, which includes a quantum dot, on the reflection patterns; and

forming a cover inorganic layer on the window layer,

wherein the light-blocking layer and the bezel layer are simultaneously patterned.

2. The method of claim 1 , wherein the first material is a same material as the second material.

3. The method of claim 1 , wherein one of the reflection patterns is formed by a same process as a process for the partition wall layer.
