Abstract
A display structure includes a liquid crystal module, and a light guide layer arranged on a surface of the liquid crystal module, first light-emitting devices arranged at an edge of one end portion of the light guide layer, and a transmittance-controllable layer arranged on a surface of the light guide layer opposing the liquid crystal module. The light-emitting devices are configured to emit light into the light guide layer, and thus the light emitted by the light-emitting devices is transmitted within the light guide layer. The transmittance-controllable layer may have light transmittance characteristics which change depending on an external stimulus applied thereto.
