Abstract
A display device, particularly a liquid crystal display, has spacing elements (10) arranged uniformly distributed between two parallel support plates (1, 2). These spacing elements (2) bear a layer of adhesive (11) and are bonded to both support plates (1, 2), precisely in the same way as in the spacing frame (4) is. In this way, the support plates (1, 2) do not bulge toward the outside. In the manufacture of the display device, the spacing frame (4) is first applied onto a support plate (2) followed then by the spacing elements (10). After the second spacing plate (1) has been placed on top, the parts are bonded together under pressure and temperature.
Claims9
A method for producing of a display device, particularly a liquid crystal display, including two support plates which are parallel to each other, and a medium which can be switched between two optically different states enclosed between the two plates, and wherein the support plates are spaced apart by an outer spacing frame;
- the method comprising the steps of
- forming spacers of such a size and nature that they are invisible to the eye,
- providing the spacers between the support plates,
- uniformly distributing the spacers in the viewing field between the support plates,
- bonding the plates to each other by a plurality of the spacers between the support plates,
- the method including the steps of coating the spacers with two components of a two-component adhesive, and separating components of the adhesive from each other by a barrier layer.

- bonding the plates to each other by a plurality of the spacers between the support plates,
- the method further comprising the steps of coating the spacers with an adhesive layer before they are introduced between the support plates, and encapsulating the adhesive layer on its outer side, the encapsulating layer decomposing under pressure and temperature with the bonding to the support plates.
