Abstract

The invention relates to a light display box (1) for viewing transparent pictures (3), having a light-transmitting plate (2), which can be illuminated from the rear, for supporting the pictures (3), as well as means (6, 7, 8, 10) for fading in the illuminated field of this plate (2) in accordance with the formats of the respectively supported pictures (3). Arranged between the picture plane and light source (5) is an electrochromic layer (10) whose transmission is switched by individually controllable, light-transmitting electrode strips (6, 7) whose width is selected in accordance with the desired accuracy for fading in. <IMAGE>
