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.

Abstract: An input sensing device includes driving electrodes and sensing electrodes, and an analog front-end which processes sensing signals from the sensing electrodes to output a differential output value. The analog front-end includes a first charge amplifier which differentially amplifies first and second sensing signals from two sensing electrodes to first and second input terminals, thus outputting first and second differential signals through first and second output terminals, a second charge amplifier which differentially amplifies the first and second differential signals, thus outputting third and fourth differential signals, a first demodulation circuit which filters the first and second differential signals in a first mode and filters each of the third and fourth differential signals in a second mode, and a first analog-to-digital converter which outputs a first sensing value based on at least one output signal of the first demodulation circuit.

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.
