Abstract
(EN)
An image display device (10) is provided with a sub-display panel (30) and a main display panel (20). The sub-display panel (30) includes a liquid crystal cell (31) and a polarizing plate (32) that is disposed along at least one of the principal surfaces of the liquid crystal cell (31). The main display panel (20) includes a liquid crystal cell (21) and a polarizing plate (22) that is disposed along at least one of the principal surfaces of the liquid crystal cell (21). The main display panel (20) is disposed so as to overlap with the sub-display panel (30) in a vertical direction with respect to the principal surfaces of the sub-display panel (30). The sub-display panel (30) is characterized by being curved toward the main display panel (20) in the case in which the sub-display panel (30) is subjected to heat.

L'invention concerne un dispositif d'affichage d'image (10) pourvu d'un panneau d'affichage secondaire (30) et d'un panneau d'affichage principal (20). Le panneau d'affichage secondaire (30) comprend une cellule à cristaux liquides (31) et une plaque de polarisation (32) qui est disposée le long d'au moins l'une des surfaces principales de la cellule à cristaux liquides (31). Le panneau d'affichage principal (20) comprend une cellule à cristaux liquides (21) et une plaque de polarisation (22) qui est disposée le long d'au moins l'une des surfaces principales de la cellule à cristaux liquides (21). Le panneau d'affichage principal (20) est disposé de façon à chevaucher le panneau d'affichage secondaire (30) dans une direction verticale par rapport aux surfaces principales du panneau d'affichage secondaire (30). Le panneau d'affichage secondaire (30) est caractérisé en ce qu'il est incurvé vers le panneau d'affichage principal (20) dans le cas où le panneau d'affichage secondaire (30) est soumis à de la chaleur.
