The invention proposes a display device having a liquid crystal panel, a carrier and a cover glass, wherein the liquid crystal panel is fastened to the carrier by means of a first flexible fastening element, characterized in that the cover glass can be fastened to the carrier by means of a second fastening element.
The proposed display device has the advantage that mechanical tensions or mechanical stresses acting on the system, in particular on the liquid crystal panel, for example due to thermal deformations, twists or deformations, can be reduced or reduced. Therefore, the load applied to the system can be particularly remote from the liquid crystal panel. Thereby, in particular, undesired optical effects can be reduced or avoided. For example, undesirable optical effects may result due to the non-uniform transmission of background-illuminated light through the system caused by the optical anisotropy altered by mechanical loading, resulting in a non-uniform distribution of brightness across the panel. The undesired optical effect may be, for example, the Mura effect, wherein this effect may be reduced, in particular, with the proposed display device. In addition, mechanical tension or mechanical stress acting on the cover glass can be reduced. In other words, for example, mechanical tensions or stresses can be better distributed in the system, so that in particular the display quality of the display device can be improved and/or the stability of the display device can be improved.
In a further embodiment, the cover glass can be fastened to the carrier by means of a second fastening element in such a way that a pressure is exerted by the cover glass on the liquid crystal panel. As a result, mechanical tensions or stresses in or on the display device can advantageously be better distributed to the individual components. For example, stress or load acting on the liquid crystal panel and/or the cover glass can be reduced or lowered, whereby display quality of image display of the display device and/or stability of the display device can be improved, in particular.
In a refinement, the pressure applied to the liquid crystal panel can act in such a way that pressure is applied to the first flexible fastening element via the liquid crystal panel. Advantageously, mechanical tensions or stresses in or on the display device can thus preferably be better distributed over the individual components. For example, stress or load applied to the liquid crystal panel and/or the cover glass can be reduced or decreased, whereby display quality of image display of the display device and/or stability of the display device can be improved, in particular.
Advantageously, the first flexible fastening element can be designed as a flexible fastening element that can be elastically and/or plastically deformed.

In an exemplary embodiment, the first flexible fastening element is connected to the carrier and/or to the liquid crystal panel by means of a first cohesive connection, in particular an adhesive connection. Thereby, the liquid crystal panel can be firmly fastened to the bracket, in particular by means of the first flexible fastening element. Further, mechanical stress or load acting on the liquid crystal panel and/or the cover glass can be advantageously reduced or reduced. This can improve, in particular, the display quality of the display device and/or the stability of the display device.
In a further embodiment, the second fastening element is connected to the carrier and/or the cover glass by means of a second cohesive connection, in particular an adhesive connection. In particular, the cover glass can thereby be firmly fastened to the carrier by means of the second fastening element. Further, mechanical stress or load acting on the liquid crystal panel and/or the cover glass can be advantageously reduced or reduced. This can improve, in particular, the display quality of the display device and/or the stability of the display device.
Preferably, the liquid crystal panel arranged on the support by the first flexible fastening element and the support together form an area that is closed with respect to the environment of the display device. Thereby, the liquid crystal panel can be firmly fastened to the bracket, in particular by means of the first flexible fastening element.

In a refinement, the liquid crystal panel and the cover glass can be arranged adjacent to one another with their respective largest side faces of the liquid crystal panel and the cover glass. This can improve, in particular, the display quality of the display device and/or the stability of the display device.
In an advantageous embodiment, an optical bonding material may be arranged between the cover glass and the liquid crystal panel. This can improve, in particular, the display quality of the display device and/or the stability of the display device. In addition, the cover glass may be securely disposed on the liquid crystal panel. In particular, a light beam radiated from the background illumination through the liquid crystal panel to the cover glass can be radiated through the optical bonding material, wherein the light beam is, for example, not and/or hardly and/or according to the desired function deflected or influenced.
