Abstract:
1. A color filter substrate, comprising: a display layer includes a plurality of openings separated from each other, shading regions disposed between the openings that displays images, color filters in the openings, and a black matrix in the shading regions; and a viewing angle control layer with an electrochromic pattern that adjusts the transmission/interception of light incident from wide viewing angles depending on a magnitude of a voltage applied to the electrochromic pattern, wherein the viewing angle control layer includes: a first transparent electrode and a second transparent electrode spaced apart from each other so as to have a predetermined gap in a vertical direction; the electrochromic pattern on the first transparent electrode, whose transmissivity changes according to an electric field formed between the first and second transparent electrodes; and an electrolyte with ions involved in an electrochromic reaction of the electrochromic pattern that fills the space between the first transparent electrode and the second transparent electrode.
