摘要： Provided is an optical sensor having such a novel structure that even if an intrinsic semiconductor region has a short substantial length in a direction parallel with a forward direction of a photodiode, a light receiving area can be ensured, whereby light detection sensitivity can be improved; and a liquid crystal panel including the optical sensor. The optical sensor includes: a photodiode (26) provided with a semiconductor film (28) having a p-type semiconductor region (28p), an intrinsic semiconductor region (28i), and an n-type semiconductor region (28n); a first gate line (38a) formed above the intrinsic semiconductor region (28i), a negative voltage being applied to the first gate line; and a second gate line (38b) formed above the intrinsic semiconductor region (28i), a positive voltage being applied to the second gate line, wherein a predetermined clearance is formed between the first gate line (38a) and the second gate line (38b), above the intrinsic semiconductor region (28i).
