Abstract
(EN)
The purpose of the present embodiment is to provide a display device such that a reduction in display quality can be suppressed. A display device according to the present embodiment comprises a display panel provided with a polymer-dispersed liquid crystal layer, and a light-emitting module provided along a side surface of the display panel, the light-emitting module being provided with a first light source having a first light emission point, a second light source having a second light emission point that is the same color as the first light emission point, a first optical waveguide provided between the first light source and the side surface, and a second optical waveguide that forms a contact part for contacting the first optical waveguide and that is provided between the second light source and the side surface, the first optical waveguide and the second optical waveguide being arranged in a first direction, and the distance along the first direction between the contacting part and the first light emission point being equal to the distance along the first direction between the contacting part and the second light emission point.
