摘要： An optical sensor circuit in accordance with the present invention detects, based on a change in the amount of light received when a pointer (P) is placed in a coordinate detection area (2) through which light from a light source (3) passes, coordinates of a position of the pointer (3) in the coordinate detection area (2). A first optical sensor circuit including an optical sensor element (41), which receives a larger amount of light due to its position relative to the light source (3), has a first wire to which a refresh signal (Shield_A) is supplied, the refresh signal (Shield_A) initializing a threshold characteristic that determines light sensitivity of the optical sensor element (41); whereas a second optical sensor circuit including an optical sensor element (42), which receives a smaller amount of light, has a second wire to which a refresh signal (Shield_B) is supplied independently of the refresh signal (Shield_A), the refresh signal (Shield_B) initializing a threshold characteristic of the optical element (42).

摘要： A source and drain electrode layer (3s/3d) of an oxide TFT element (3) is formed by a first conductive layer. A gate electrode (3g) of the oxide TFT element (3) and a gate electrode (5g) of an a-Si TFT element (5) are formed by a single conductive layer, that is, a second conductive layer. A source and drain electrode layer (5s/5d) of the a-Si TFT element (5) is formed by a third conductive layer. The third conductive layer is formed above the second conductive layer in a thickness direction in which each conductive layer is stacked on an insulating substrate (2). Further, the first conductive layer is formed below the second conductive layer in the thickness direction. Therefore, it is possible to provide a circuit board that can have an improved degree of integration of transistor elements formed on the insulating substrate.

摘要： It is an object of the present invention to provide a display device equipped with a display panel that is provided with a photo-detection section with improved accuracy of detecting a touch position. A display panel (11) of an organic EL display device (10) includes a photo-detection section (40) that detects reflected light when a screen is touched by a finger or the like. The photo-detection section (40) includes a photodiode (41) that receives the reflected light, and an output amplifier (42) that outputs an output voltage corresponding to the amount of the received light. If an a-Si diode is used for such a photodiode (41), a sufficiently large signal difference in sensitivity between the bright state and the dark state can be achieved. Also, if a p-Si amplifier is used for the output amplifier (42), the output voltage becomes the saturation voltage at the time of read-out. This allows the p-Si amplifier to directly output the large sensitivity difference detected by the a-Si diode as a large difference in the output voltage.
