An electronic device includes a first substrate, a first conducting layer disposed on the first substrate, a first insulating layer disposed on the first conducting layer, a second conducting layer disposed on the first conducting layer, and a second insulating layer disposed on the first insulating layer. The second conducting layer includes a first conductive portion electrically connected to the first conducting layer through a first opening of the first insulating layer. The second insulating layer includes protruding patterns protruding from a surface of the first insulating layer. The protruding patterns include a first protruding pattern and a second protruding pattern separated from each other in a top view. In the top view, the first opening is disposed between the first protruding pattern and the second protruding pattern along a first direction, and the first conductive portion is spaced apart from the first protruding pattern and the second protruding pattern.

The present invention relates to a layer structure, preferably a hinge, particularly preferably a book cover, very particularly preferably a book cover for identification and security documents, comprising at least one outer layer a) containing at least one thermoplastic elastomer, preferably a thermoplastic polyurethane, and at least one layer b) containing at least one material selected from the group consisting of a polymer, a metal, a textile, a paper and a synthetic paper, or a combination of at least two of these, and also relates to a laminate comprising the above layer structure and to the method for producing same. The invention further relates to the use of the layer structure and/or laminate for the production of a hinge, preferably a multilayer book cover, especially for security and identification documents.

A display device includes a display panel, and a pattern glass disposed on the display panel and including a first non-pattern portion, a pattern portion, and a second non-pattern portion, which are arranged in a first direction. The pattern portion includes a plurality of patterns having a shape and arranged in the first direction and a second direction intersecting the first direction, and openings defined through the pattern glass between the plurality of patterns adjacent to each other. Each of the openings has a symmetrical shape with respect to a third direction intersecting a plane defined by the first and second directions based on a symmetry axis extending in the second direction. The symmetry axis passes through a midpoint of a thickness of the pattern glass.
