/Display Apparatus Having A Light-blocking Pattern
Abstract

A display apparatus includes a light-blocking pattern on a pixel area of a device substrate; an upper buffer layer on the light-blocking pattern extending on a bending area of the device substrate; a switching thin film transistor on the upper buffer layer including a first semiconductor pattern spaced away from the light-blocking pattern; a separation insulating layer on the first semiconductor pattern extending on the upper buffer layer of the bending area; a driving thin film transistor on the separation insulating layer of the pixel area including a second semiconductor pattern overlapping with the light-blocking pattern; a bending open hole on the bending area including a first bending hole exposing a portion of the upper buffer layer and a second bending hole in the first bending hole; and an intermediate electrode on the separation insulating layer connected to the light-blocking pattern through an intermediate contact hole.
