A liquid crystal display includes a liquid crystal display panel and a backlight unit. The backlight unit includes a first transistor generating a power voltage supplied through a power line as a driving current based on a driving voltage supplied to a gate electrode of the first transistor, a light emitting element emitting light by the first transistor, a second transistor connected to the first transistor in a current mirror form, a capacitor storing, and at least two switching transistors that equally respond to a selection signal supplied through a selection line and form the same discharge path, so that the power voltage supplied through the power line is sunk to a constant current unit and the driving voltage is stored in the capacitor. |
