摘要： In a manufacturing process of a display device, hydrogenation in an I layer of photodiodes D1 and D2 is progressed less than that in a channel portion of a pixel TFT, and a defect density due to dangling bonds not terminated in the I layer of the photodiodes D1 and D2 is made higher than a defect density in the channel portion of the pixel TFT. Thus, while suppressing a leakage current of the pixel TFT, the sensitivity of the photodiodes D1 and D2 to light is improved. Moreover, a gate electrode is provided above an i region of a pin-type optical sensor diode with an insulating film interposed therebetween. Thus, a gate voltage can control a threshold of a bias voltage when a current starts to flow into the optical sensor diode and a leakage current is prevented from flowing into the optical sensor diode.

摘要： In order to detect pressure of a light source device against a display screen of a display device, the light source device changes an area of a light receiving region on the display screen in response to a degree of pressure of a tip of the light source device against the display screen. Meanwhile, a signal processing unit of the display device calculates a distance between a light transmission unit of the light source device and the display screen.

摘要： An organic EL display panel includes a substrate, pixel electrodes, a common electrode, signal lines, power supply lines, thin-film transistors, scan lines, organic EL elements and storage capacitors. To obtain a full color image by light emissions of the organic EL elements, a red (R) emitter, a green (G) emitter and a blue (B) emitter are patterned correspondently with the pixel electrodes and arranged in this order along the gate line direction. The emitters are patterned such that each pair of the red (R) emitter, the green (G) emitter and the blue (B) emitter which are adjacent to each other along the gate line direction overlap each other to define a light-emitting layer overlap region, where colors of light components which exit the organic EL elements and pass through the emitters are mixed, between the adjacent organic EL elements arranged along the gate line direction. At least one of the thin-film transistor and the storage capacitor is arranged in the light-emitting layer overlap region.
