<p>The purpose of the present invention is to provide a liquid crystal panel, wherein optical detection sensitivity of a photodiode is improved with a simple structure. Provided is a liquid crystal panel, which is provided with: a photodiode (18), which is formed on a substrate (22), and is provided with a semiconductor film (24) for a diode, said semiconductor film having a p-type semiconductor region (24p), an intrinsic semiconductor region (24i), and an n-type semiconductor region (24n); and covering insulating films (30, 32a), which are formed to cover the photodiode (18). The covering insulating films (30, 32a) are provided with: a first covering insulating film (30) formed on the photodiode (18); and a second covering insulating film (32a), which is formed on the first covering insulating film (30), and has a refractive index larger than that of the first covering insulating film (30). The thickness of the first covering insulating film (30) is 1/4 or more of the wavelength of light inputted to the photodiode (18).</p> |
