摘要： A display apparatus includes: a display unit that displays a two-dimensional image; and a variable lens array disposed to face the display unit, wherein the variable lens array includes a variable phase difference layer that receives incident linearly polarized light polarized in a first direction and allows the linearly polarized light polarized in the same direction to exit or allows linearly polarized light polarized in a second direction switched from the first direction and different therefrom to exit, and an optically anisotropic layer that receives the light having exited out of the variable phase difference layer and works as a lens array for one of the light polarized in the first direction and the light polarized in the second direction whereas working as a transparent layer for the other light.

摘要： A common electrode for a display, which is originally provided in a liquid crystal display element, is also used as one (drive electrode) of a pair of electrodes for a touch sensor, and the other (detection-electrode-for-the-sensor) of the pair of electrodes is newly formed. An existing common drive signal as a drive signal for display is used in common for a drive signal for the touch sensor. A capacitance is formed between the common electrode and the detection-electrode-for-the-sensor, and touch detection is performed by utilizing a change of this capacitance caused by a finger touch of a user. Thus, a display device with a touch sensor is also applicable to a mobile device in which electric potential of the user is inconstant in many cases. The newly-provided electrode is only the detection-electrode-for-the-sensor, and it is unnecessary to newly prepare a drive signal for the touch sensor.

摘要翻译： 最初设置在液晶显示元件中的用于显示器的公共电极也用作一对用于触摸传感器的电极的一个（驱动电极），另一个（用于传感器的检测电极 ）新形成。 作为用于显示的驱动信号的现有公共驱动信号通常用于触摸传感器的驱动信号。 在公共电极和传感器检测电极之间形成电容，并且通过利用由用户的手指触摸引起的该电容的变化来执行触摸检测。 因此，具有触摸传感器的显示装置也适用于许多情况下用户的电位不变的移动装置。 新提供的电极只是用于传感器的检测电极，并且不需要重新准备用于触摸传感器的驱动信号。
