A constitution for a display device that can obtain sufficient fluorescent light emission without making a light adjusting layer thick and without affecting the characteristics of the light adjusting layer is obtained. A display device (1) is provided with a pair of substrates (10, 20), a light adjusting layer (30) sandwiched between the pair of substrates (10, 20) and constituted so as to be switchable between a transparent state and a scattering state, and spacers (40) that regulate the spacing between the pair of substrates (10, 20). The spacers (40) contain a fluorescent dye (42) that absorbs light and emits fluorescent light. L'invention concerne une constitution d'un dispositif d'affichage qui peut obtenir une émission suffisante de lumière fluorescente sans rendre épaisse une couche d'ajustement de lumière et sans affecter les caractéristiques de la couche d'ajustement de lumière. Un dispositif d'affichage (1) comporte une paire de substrats (10, 20), une couche d'ajustement de lumière (30) prise en sandwich entre la paire de substrats (10, 20) et constituée afin d'être commutable entre un état transparent et un état de diffusion et des espaceurs (40) qui régulent l'espacement entre la paire de substrats (10, 20). Les espaceurs (40) contiennent un colorant fluorescent (42) qui absorbe la lumière et émet de la lumière fluorescente.
