Abstract:
A display apparatus is provided that prevents shortening of the life of the luminescent elements and has a superior contrast ratio. The display apparatus is composed by forming a plurality of luminescent elements on a substrate and providing bank sections between each of the luminescent elements. The bank sections are formed from a first bank layer located on the side of the substrate and a second bank layer formed on the first bank layer. A light blocking layer is then provided between the first bank layer and the second bank layer.
