Display device

Abstract

A display device includes a display panel and a backlight unit. The display panel is configured to display an image. The backlight unit is configured to provide light to the display panel. The display panel includes an array substrate including a plurality of pixel areas, an opposite substrate facing the array substrate, a liquid crystal layer disposed between the array substrate and the opposite substrate, and a wavelength-selective transflective member disposed on the array substrate or the opposite substrate.

What is claimed is: 
     
         1 . A display panel, comprising:
 a wavelength-selective transflective member configured to transmit light of at least one first range of wavelengths and reflect light of at least one second range of wavelengths; and   a plurality of color filters disposed on the wavelength-selective transflective member,   wherein the wavelength-selective transflective member comprises an opening overlapping, in a plan view, at least one of the plurality of color filters, and overlaps, in the plan view, at least two of the plurality of color filters.   
     
     
         2 . The display panel of  claim 1 , wherein the plurality of color filters comprise:
 at least one red color filter;   at least one green color filter; and   at least one blue color filter.   
     
     
         3 . The display panel of  claim 1 , wherein the color of the one color filter disposed in association with the opening corresponds to the color of light associated with the second range of wavelengths. 
     
     
         4 . The display panel of  claim 1 , wherein light reflected by the wavelength-selective transflective member is caused, at least in part, to be redirected through the opening. 
     
     
         5 . The display panel of  claim 1 , wherein the plurality of color filters is sequentially arranged with respect to one another. 
     
     
         6 . The display panel of  claim 1 , wherein the wavelength-selective transflective member comprises a plurality of sub-wavelength selective transflective members, and wherein:
 a first one of the plurality of sub-wavelength selective transflective members is disposed in association with a first one of the plurality of color filters and is configured to transmit light of a range of wavelengths corresponding to the color of the first one of the plurality of color filters;   a second one of the plurality of sub-wavelength selective transflective members is disposed in association with a second one of the plurality of color filters and is configured to transmit light of a range of wavelengths corresponding to the color of the second one of the plurality of color filters; and   a third one of the plurality of sub-wavelength selective transflective member is disposed in association with a third one of the plurality of color filters and is configured to transmit light of a range of wavelengths corresponding to the color of the third one of the plurality of color filters.   
     
     
         7 . The display panel of  claim 6 , wherein the plurality of sub-wavelength selective transflective members are disposed on the same layer. 
     
     
         8 . The display panel of  claim 6 , wherein the plurality of sub-wavelength selective transflective members are disposed on different layers. 
     
     
         9 . The display panel of  claim 8 , wherein the wavelength-selective transflective member further comprises:
 a first protective layer covering the first sub-wavelength selective transflective member;   a second protective layer disposed on the first protective layer, the second protective layer covering the second sub-wavelength selective transflective member; and   a third protective layer disposed on the second protective layer, the third protective layer covering the third sub-wavelength selective transflective member.   
     
     
         10 . The display panel of  claim 1 , further comprising:
 a liquid crystal layer,   wherein the wavelength-selective transflective member is disposed between the liquid crystal layer and the plurality of color filters.   
     
     
         11 . The display panel of  claim 1 , further comprising:
 a liquid crystal layer,   wherein the liquid crystal layer is disposed between the plurality of color filters and the wavelength-selective transflective member.
