Method of manufacturing a display device

Method of manufacturing a display device (1) having a display window (3) and in front of the display window an auxiliary transparent plate (15), in which method the display window (3) and the transparent plate (15) are positioned at some distance from each other, the display window and the auxiliary are attached to each other around the edges by a seal (17), the seal having at least one opening (18), the volume between the display window and the auxiliary plate being filled with curable material (16) where after the curable material is cured, characterized in that the display window (3) and the auxiliary plate (15) are oriented at an first angle of tilt (α1) to the horizontal direction, preferably substantially vertically, the volume is partially filed with uncured resin up to a selected level height h, the opening (18) being at or near the highest point, thereafter the angle of tilt is reduced to a second angle α2 smaller than the first angle α1, and when the resin has reached the opening the resin near the opening is cured to plug the opening, where after the angle of tilt is reduced to a third angle α3, preferably substantially zero, and the rest of the resin is fully cured.
