The nanocrystal layer includes nanocrystals, which are crystallized and dispersed, and a barrier layer, which buries the nanocrystals. When a program voltage is applied, charges are trapped in the nanocrystals, and the OLED emits light at a predetermined luminance with the application of a read voltage. Data signals are sequentially applied to all pixels of the display panel to express desired grayscales. The pixels of the display panel receive the read voltage and emit light at the same time.
