DISPLAY APPARATUS

A display apparatus includes a substrate having a first substrate, a second substrate, and an inorganic insulating layer between the first substrate and the second substrate. A first buffer layer is on the substrate, wherein the first buffer layer includes n+1 layers, and 'n' is 0 or an even number. A first thin film transistor, a second thin film transistor, and a storage capacitor are each on the first buffer layer. The first thin film transistor includes a first active layer formed of a low temperature poly silicon material. The second thin film transistor includes a second active layer formed of an oxide semiconductor material. The storage capacitor includes a first capacitor electrode and a second capacitor electrode.
