A display device configured such that a variation in the brightness of illumination light transmitted through a display element is suppressed as much as possible.  The display device comprises: a light source unit (27) having light sources (25) arranged on a wiring board (24); a lens member (26) having lenses (26b) for collecting illumination light from the light sources (25) and mounted corresponding to the light sources (25); and a display element (21) transilluminated with light emitted through the lenses (26b).  The lens member (26) has formed thereon a connecting section (26c) for bridging a boundary portion (D3) between the lenses (26b). L'invention porte sur un dispositif d'affichage configuré de telle sorte qu'une variation de la brillance d'une lumière d'éclairage transmise à travers un élément d'affichage est supprimée autant que possible. Le dispositif d'affichage comprend : une unité de source de lumière (27) ayant des sources de lumière (25) disposées sur une carte de câblage (24) ; un élément de lentille (26) ayant des lentilles (26b) pour collecter une lumière d'éclairage provenant des sources de lumière (25) et monté de façon correspondante aux sources de lumière (25) ; et un élément d'affichage (21) trans-éclairé par une lumière émise à travers les lentilles (26b). L'élément de lentille (26) a une section de connexion (26c) formée sur celui-ci pour ponter une partie de frontière (D3) entre les lentilles (26b).
