A photosensor is disposed in each pixel, and the brightness is adjusted for each pixel depending on the light quantity of an organic EL element. The adjustment of brightness is realized by making the current amount of a pixel with a high brightness small in accordance with a pixel with a small light emission amount. Thus, low power consumption can be achieved, and the unevenness of brightness can be corrected. By disposing the photosensor to configure a photoreceptor circuit in each pixel, the unevenness of brightness is corrected. Further, it becomes possible to correct brightness in a brightness half-life. Hence, a longer lifetime can be achieved.

A photosensor and a display unit are fabricated on the same substrate. Input coordinates are identified by comparing the light quantities at positions (pixels) which is and is not touched by a finger or the like by use of a comparison circuit. Thus, TFTs to form the photosensor can be fabricated on the same substrate in the same process, and also reductions in manufacturing cost and the number of parts can be realized. A region required for disposing a sensor in the circumference becomes unnecessary, thus realizing the miniaturization of the device. Moreover, since a region to be a blind spot is eliminated in the display unit, it is possible to utilize the display unit effectively. It is possible to improve the precision of an input recognition and to uniformly perform detection all over the display unit. Furthermore, since the photosensor is constituted of a photoreceptor circuit which is capable of adjusting the sensitivity of receiving light, it is possible to make the sensitivity of receiving light (detection) uniform in the display unit.

In order to realize a surface inspection apparatus capable of inspecting a contaminant particle and a defect with a uniform sensitivity without depending on a rotation angle in a primary scan direction even in the case where intensity of scattered light, which is generated derived from the contaminant particle and the defect existing on the surface of a semiconductor wafer or adjacent to the surface, has anisotropy which depends on an illumination direction; light from a light source 11 becomes two illumination beams 21 and 22 by a beam splitter 12, the beams being irradiated onto a semiconductor wafer 100 from two mutually substantially orthogonal azimuthal angles having substantially equal elevation angles to form illumination spots 3 and 4.

This makes it possible to inspect a contaminant particle, defect, and the like with a uniform sensitivity without depending on a rotation angle in a primary scan direction even in the case where intensity of the scattered light generated derived from the contaminant particle, defect, and the like depends on the illumination direction.
