Display device and method of fabricating the same

A display device comprising:

• a display panel having a display area and a non-display area;
• and
• a viewing angle control layer comprising a plurality of viewing angle control patterns spaced apart from one another in the display area,
• wherein each of the viewing angle control patterns comprises a transparent insulating pattern and a multi-layered sidewall on a side surface of the transparent insulating pattern,
• wherein the multi-layer sidewall comprises a first metal nitride layer, a second metal nitride layer, and a metal layer between the first metal nitride layer and the second metal nitride layer, and
• wherein the first metal nitride layer, the metal layer, and the second metal nitride layer are either AlN, Al, AlN, respectively, or TiN, Ti, TiN, respectively.

A method of fabricating a display device, the method comprising:

• forming a plurality of transparent insulating layer patterns spaced apart from one another at a uniform distance on a display panel;
• forming a light-absorbing layer by sequentially stacking a first metal nitride layer, a metal layer, and a second metal nitride layer on the display panel and covering the plurality of transparent insulating layer patterns, the first metal nitride layer, the second metal nitride layer, and the metal layer each comprise Al or Ti;
• and
• etching the light-absorbing layer on upper surfaces of the plurality of transparent insulating layer patterns and between adjacent ones of the plurality of transparent insulating layer patterns by anisotropic etching.
