ABSTRACT:
A photo-luminescent (PL) liquid crystal display (LCD) including a blue dichroic mirror layer disposed under a light emitting layer is provided. Visible light generated from the light emitting layer is mostly reflected to the front side of the PL LCD, thereby increasing the light utilization efficiency thereof. A blue PL quantum dot layer is formed in blue light regions, thereby improving a narrow viewing angle and an orientation in blue pixels. An ultraviolet (UV) filter blocking UV light in the ambient light is formed to protect the light emitting layer from the excitation caused by external light, thereby preventing degradation of contrast caused by an undesired light emission.
