Abstract
According to an aspect, a display apparatus includes: a first light-transmissive substrate; a second light-transmissive substrate arranged to face the first light-transmissive substrate; a liquid crystal layer including polymer dispersed liquid crystals sealed between the first light-transmissive substrate and the second light-transmissive substrate; at least one light-emitting device arranged to face at least one of a side surface of the first light-transmissive substrate or a side surface of the second light-transmissive substrate; and at least one reflector arranged on at least one of a side surface of the first light-transmissive substrate or a side surface of the second light-transmissive substrate, the side surface of the first or second light-transmissive substrate being on an opposite side of the side surface of the first or second light-transmissive substrate to which the at least one light-emitting device faces, and configured to reflect light at the side surface on the opposite side.
