Abstract
A display apparatus having color filters and a light-shielding element is provided. The color filters and the light-blocking element are disposed on a surface of a device substrate. The color filters on a display area of the device substrate can include a dye. The light-blocking element on a bezel area of the device substrate can have a stacked structure of a first blocking filter layer and a second blocking filter layer. The first blocking filter layer and the second blocking filter layer can include the different dye. In the display apparatus, process efficiency can be improved, and the overall thickness can be reduced.
