Display devices and related methods involving patterned phase retarding
Display devices and related methods involving patterned phase retarding are provided. A representative display device includes: a backlight unit, having a light source and a color conversion layer having an alignment direction, the light comprising a first light exhibiting a first upstream polarization ratio, a second light exhibiting a second upstream polarization ratio, and a third light exhibiting a third upstream polarization ratio; and a patterned phase retarder positioned to receive the light, having a plurality of half-wave regions to alter polarization of light passing therethrough, and a plurality of free regions to pass light without altering the polarization; wherein polarization ratio (PR) is defined by PR=(I∥−I⊥)/(I∥+I⊥); and wherein the first upstream polarization ratio exhibits a first sign, and both the second upstream polarization ratio and the third upstream polarization ratio exhibit a second sign opposite the first sign.
