    • A display device for detecting a detected object contacting in the display surface is provided to improve the S/N(Signal-to-Noise) ratio of a detection result obtained from an operation unit by the display device. A pair of light receiving devices of a plurality of sensor areas performs the photoelectric conversion of incident light. An optical filter unit(60) blocks and absorbs the incident light of the visible light area. The optic filter unit transmits the incident light of the non-visible light reverse. A light blocking unit(70) of the light absorptiveness is arranged in one sensor area of a plurality of sensor areas between a second light receiving unit. The light shielding unit blocks the incident light. An operation unit calculates the difference between the output signal of the output signal of the first light receiving unit and the second light receiving unit.
    • 提供一种用于检测在显示面上接触的被检测物体的显示装置,以提高由显示装置从操作单元获得的检测结果的S / N(信噪比)。 多个传感器区域中的一对光接收装置执行入射光的光电转换。 光滤波器单元(60)阻挡并吸收可见光区域的入射光。 光滤波器单元将不可见光的入射光反射。 在第二光接收单元之间的多个传感器区域的一个传感器区域中布置有光吸收性的遮光单元(70)。 遮光单元阻挡入射光。 操作单元计算第一光接收单元的输出信号和第二光接收单元的输出信号之间的差。
