Abstract: A display apparatus includes a light source and a display panel. The light source emits a light. The display panel includes a first polarizing plate, a second polarizing plate, a third polarizing plate, and a shutter. The first polarizing plate receives the light provided from the light source and incident to a lower portion thereof and linearly polarizes the light incident thereto. The second polarizing plate is disposed on the first polarizing plate and circularly polarizes the light exiting through the first polarizing plate. The third polarizing plate is disposed on the second polarizing plate and linearly polarizes the light incident thereto. The shutter is disposed on the first polarizing plate and mechanically deforms in a thickness direction of the first polarizing plate in response to an electrical signal. The display apparatus displays a grayscale in accordance with mechanical deformation of the shutter.

Abstract: A display apparatus is provided. The display apparatus includes a first light source unit comprising a first light source that emits light having a first spectral band and a photo-converter that converts the light having the first spectral band to a first color light. A spectral band of the first color light is different from the first spectral band of the light emitted from the first light source. The display apparatus also includes a second light source unit comprising a second light source that emits light having a second spectral band. The light having the second spectral band corresponds to a second color light, and has a same color as the light having the first spectral band. A spectral band of the second color light is different from the spectral band of the first color light.
