This U.S. non-provisional patent application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2021-0046747, filed on Apr. 9, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The present disclosure relates to a display panel, and in particular, to a display panel including a light control pattern.
Display panels may be classified as a transmission-type display panel and an emission-type display panel. A transmission-type display panel uses a separate light source to produce a visible image. An emission-type display panel does not require a separate light source to produce a visible image. In general, to produce a color image, the display panel includes three or more different kinds of light control patterns. The light control pattern may be transparent to only the source light in a specific wavelength range or may convert the color of the source light. Some light control patterns may change the optical characteristics of the source light, but not the color of the source light.
An embodiment of the inventive concept provides a display panel with increased display quality.
