Abstract
The present invention relates to a glass pane construction, particularly bullet proof glass pane, to be used in a motor vehicle, having several transparent panes and layers made of glass, ceramic or synthetic material, which are connected in a layered manner connected to each other in a laminate, electrical controllable or switchable electrochromic layer means for electrical controlling or switching of the light transparency of the glass pane construction or of the bullet proof pane, wherein a laminar transparent UV filtering layer means for filtering of striking ultraviolet (UV) radiation is provided so that none or only a part of the UV radiation passes to the electrochromic layer means.
