    • Provided is a photoluminescence liquid crystal display (LCD) using a light source emitting polarized light. The photoluminescence LCD may include a light source emitting polarized light, a light control unit including a liquid crystal layer having a plurality of pixel regions and modulating a polarization direction of the polarized light individually with respect to each of the pixel regions, a polarizer transmitting the modulated light only when the polarized light has a polarization direction, and a photoluminescence layer excited by the light transmitted through the polarizer and emitting excitation light by photoluminescence. Accordingly, an additional polarizer may not be on a rear surface of the light control unit, so that photoluminescence LCD may have a simpler structure and increased light use efficiency.
    • 提供了使用发射偏振光的光源的光致发光液晶显示器(LCD)。 光致发光LCD可以包括发射偏振光的光源,包括具有多个像素区域的液晶层并相对于每个像素区域分别调制偏振光的偏振方向的光控制单元, 仅当偏振光具有偏振方向时才产生调制光,并且由穿过偏振器的光激发的光致发光层和通过光致发光发射激发光。 因此,附加的偏振器可以不在光控制单元的后表面上,使得光致发光LCD可以具有更简单的结构和增加的光使用效率。
