Abstract

A display apparatus is provided, which includes a rigid substrate; a first carrier plate provided on a first surface of the rigid substrate; a first substrate provided on the first carrier plate, the first substrate including a thin film transistor with a drain; a light emitting assembly provided on a second surface of the rigid substrate distal to the first surface, the light emitting assembly including an anode and a light emitting layer provided successively along a direction distal to the rigid substrate; and a via hole provided penetrating the rigid substrate and the first carrier plate, the anode electrically coupled to the drain through the via hole. In the display apparatus of the present disclosure the light emitting assembly is separated from the array substrate such that when the light emitting assembly or the first substrate suffers from failure, it can be replaced easily.
