Abstract
A representative device includes: first and second substrates spaced to define a gap; a liquid crystal layer, positioned in the gap, having a plurality of display pixels configured to be switchable between an on state and an off state; a quantum dot layer positioned between the liquid crystal layer and the second substrate; a first shielding layer positioned between the first substrate and the liquid crystal layer, the first shielding layer having a plurality of first shield portions configured to prevent propagation of blue light therethrough; and a second shielding layer positioned between the liquid crystal layer and the second substrate, the second shielding layer defining a plurality of openings configured to permit propagation of the blue light therethrough; wherein each of the display pixels of the liquid crystal layer corresponds to at least one of the openings, and each of the openings corresponds to one of the first shield portions.
