Abstract: An electronic device includes a display layer and a sensor layer on the display layer. The sensor layer includes an electrode and a cross electrode. The electrode includes a plurality of first portions spaced from each other in a first direction and a plurality of second portions between the plurality of first portions. The cross electrode includes a plurality of first cross portions spaced from each other in a second direction crossing the first direction and a plurality of second cross portions between the plurality of first cross portions. The second portion includes a first pattern portion extending in the first direction and a plurality of second pattern portions extending in the second direction. A first opening is in the plurality of first portions, a second opening is in the first pattern portion, and a size of the first opening is greater than a size of the second opening.

Abstract: An electronic device includes a display layer, a sensor layer disposed on the display layer and including a first sensing pattern and a second sensing pattern spaced apart from the first sensing pattern. The first sensing pattern includes a first-first group including a first-first pattern and a first-second pattern spaced apart from the first-first pattern in a first oblique direction, a first-second group including a first-third pattern and a first-fourth pattern spaced apart from the first-third pattern in a second oblique direction crossing the first oblique direction. The second sensing pattern includes a second-first group adjacent to the first-first group and including a second-first pattern and a second-second pattern spaced apart from the second-first pattern in the second oblique direction and a second-second group including a second-third pattern and a second-fourth pattern spaced apart from the second-third pattern with the second-first group interposed therebetween in the first oblique direction.

Abstract: A liquid crystal display according to an exemplary embodiment of the present invention includes: a first substrate and an opposing second substrate; a first pixel electrode and a second pixel electrode disposed in a pixel area, on the first substrate, and including a plurality of branch electrodes; and a liquid crystal layer interposed between the first and second electrodes. Branches electrode of the first pixel electrode and the second pixel electrode are interlaced. The first pixel electrode has an extension disposed adjacent to the center of the pixel area, and a minimum distance between the extension and the adjacent branch electrode is different from an average minimum between the adjacent branch electrodes.
