Abstract
In a display device with a liquid-crystal cell (1) with two supporting panels (2, 3) and a heating device (4) and at least one pole filter (6), the pole filter (6) is kept at a distance from the heating device (4) by a transparent insulating layer (7). This avoids inadmissibly high thermal loading of the pole filter (6).
