Abstract:
Provided is a display apparatus including a liquid crystal panel and a shutter panel, wherein the shutter panel includes a shutter layer configured to change a polarizing axis of light transmitted through a selected area, a shutter polarizing layer disposed on a front surface of the shutter layer, and configured to transmit light having the polarizing axis changed by the shutter layer, and a quantum rod layer disposed on a rear surface of the shutter layer, and configured to convert a wavelength of light that is incident to the shutter panel, and to transmit light having a polarizing axis of a predetermined direction to the shutter layer. Therefore, the display apparatus may implement a local dimming structure and improve the optical efficiency.
