摘要：
An a:Si diode (7) for use in LCDs is located between two metal contacts (10, 15) which extend throughout the diode surface. This reduces the detrimental effect due to the light sensitivity of (amorphous) silicon. A MIM element (8) parallel to the diode (7) is obtained by having the metal contacts project further and by providing a thin layer of insulating material (13, 19) between these contacts.
