  • Publication number: 20100214647
    Abstract: A reflective display apparatus includes a first substrate, a second substrate, a display layer and a light shielding layer. The first substrate has a driving circuit layer and the second substrate has a transparent electrode layer opposite to the driving circuit layer. The display layer is disposed between the driving circuit layer and the transparent electrode layer. The light shielding layer has a first adhering surface and a second adhering surface, wherein the first adhering surface is adhered to the display layer and the second adhering surface is adhered to the driving circuit layer. The light shielding layer can prevent the driving circuit layer from being illuminated by external light rays, and thus display quality of the reflective display apparatus is improved.
