A liquid crystal display includes a first substrate, and a first optical conversion layer disposed on the first substrate. The first optical conversion layer includes a reflecting unit reflecting incident light, and a polarizing unit. The polarizing unit transmits light which oscillates in a first direction among the incident light, and reflects light which oscillates in a second direction different from the first direction among the incident light. The reflecting unit and the polarizing unit of the first optical conversion layer may be disposed in at least one pixel area.
