Abstract

Un dispositif d'affichage d'image (10) est pourvu : d'un cadre inférieur (140, 140a) disposé sur le côté de surface arrière d'un panneau d'affichage (102); d'une pluralité de DEL (1091) disposées sur le côté de surface avant dans le cadre inférieur (140, 140a); une plaque d'uniformité de luminance (107) qui est agencée sur le côté de surface avant des DEL (1091) de façon à recouvrir la pluralité de DEL (1091) et qui amène la lumière provenant des DEL (1091) pour devenir uniforme; une plaque de diffusion (106) disposée sur le côté de surface avant de la plaque d'uniformité de luminance (107) et utilisée pour diffuser la lumière qui a traversé la plaque d'uniformité de luminance (107); et une broche de support (200) s'étendant de manière à passer à travers la plaque d'uniformité de luminance (107) tout en étant fixée au cadre inférieur (140, 140a), ladite broche de support (200) ayant une pointe qui supporte la plaque de diffusion (106). La pointe de la broche de support (200) est formée pour avoir une forme de surface convexe.
