Abstract
(EN)
The present disclosure provides a lighting device which is arranged facing a reflective display device that performs displaying by electrically controlling light reflection, the lighting device having a plurality of light-emitting parts distributed and arranged on a transmissive substrate, wherein a light control layer is arranged that changes the radiation distribution of light emitted from the light-emitting parts, and the light-emitting parts are arranged at a period differing from the arrangement period of pixels of the display device.
