摘要:
The area occupied by a photo-sensor element may be reduced and multiple elements may be integrated in a limited area so that the sensor element can have higher output and smaller size. Higher output and miniaturization are achieved by uniting a sensor element using an amorphous semiconductor film (typically an amorphous silicon film) and an output amplifier circuit including a TFT with a semiconductor film having a crystal structure (typically a poly-crystalline silicon film) used as an active layer over a plastic film substrate that can resist the temperature in the process for mounting such as a solder reflow process. A sensor element that can resist bending stress can be obtained.

In an optical sensor device employing an amorphous silicon photodiode, an external amplifier IC and the like are required due to low current capacity of the sensor element in order to improve the load driving capacity. It to increase in cost and mounting space of the optical sensor device. In addition, noise may easily superimpose since the photodiode and the amplifier IC are connected to each other over a printed circuit board. According to the invention, an amorphous silicon photodiode and an amplifier configured by a thin film transistor are formed integrally over a substrate so that the load driving capacity is improved while reducing cost and mounting space. Superimposing noise can also be reduced.
