Abstract: A liquid crystal display includes: an upper substrate and a lower substrate spaced apart from each other, forming a cell gap therebetween. A liquid crystal layer is disposed in the cell gap between the upper substrate and the lower substrate and has liquid crystal molecules. A common electrode is disposed on the lower substrate facing the liquid crystal layer. A passivation layer is disposed on the lower substrate and covers the common electrode. Multiple pixel electrodes are disposed on the passivation layer. A planar electrode is disposed on the upper substrate facing the liquid crystal layer, and is provided with a first biased voltage. The liquid crystal molecules of the liquid crystal layer are vertically aligned at a voltage-off state. In some cases, the upper substrate has a first anchoring energy W2 and the lower substrate has a second anchoring energy W2, and W2 is weaker than W1.

Abstract: 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.
