A display device is manufactured having a display with an auxiliary plate. The display window (3) and the auxiliary plate (15) are oriented at an angle of tilt &agr;1, preferably substantially vertically, the volume in between the display window and auxiliary plate is filed up to a selected level height (h) with uncured resin, a seal (17) and an opening (18) being provided at or near the highest point. Thereafter the display window is reoriented to a more horizontal position (smaller angle of tilt &agr;2) the auxiliary plate being positioned on top of the display window inducing a flow v of curable material (16) towards the opening (18), and when the resin has reached the opening the resin near the opening is plugged, where after the angle of tilt is further reduced and the resin is fully cured.
