Abstract: An input sensing device includes a first base layer, a plurality of first sensing electrodes, a plurality of second sensing electrodes, a plurality of third sensing electrodes, and a plurality of fourth sensing electrodes. The first sensing electrodes are arranged on the first base layer along a first direction. The second sensing electrodes are arranged on the first base layer in different rows from the first sensing electrodes. The third sensing electrodes are arranged on the second sensing electrodes along a second direction different from the first direction. The third sensing electrodes overlap the second sensing electrodes. The fourth sensing electrodes are arranged on the same layer as the third sensing electrodes and overlap the first sensing electrodes. A constant voltage is applied to the third sensing electrodes during a touch pressure sensing operation.

Abstract: An optical touch film includes a sensor layer, an optical film, an adhesive layer, a separation layer, and a refractive insulating layer. The sensor layer includes touch electrodes forming a sensor. The adhesive layer is between the sensor layer and the optical film. The separation layer is on a surface of the sensor layer. The separation layer includes an organic polymer material. The refractive insulating layer is on the touch electrodes. A refractive index of the refractive insulating layer is greater than a refractive index of the separation layer.

Abstract: A display device is provided. The display device includes an anti-reflection film. The anti-reflection film includes a base film, a retardation coating layer disposed on a first side of the base film so as to delay a phase of transmitted light, and a polarizer coating layer disposed on a second side of the base film so as to allow a polarization component of the transmitted light in a specific direction to pass through, wherein the retardation coating layer and the polarizer coating layer are formed by applying a liquid crystal on the base film.
