Abstract
Abstract A liquid crystal display device is provided by forming an optical blocking layer which blocks intensive incident light leaking into switching elements. A plurality of switching elements 1 is formed on a substrate 10. A first electrode 2 is connected to and positioned over the switching element. A storage capacitor 3 is connected and positioned under the first electrode. An optical reflector 15 is formed on the first electrode. A transparent second electrode 4 is spaced apart from the optical reflector. A layer of liquid crystal material 5 is positioned between the optical reflector and the second electrode. A substantially nonconductive optical blocking layer 20 is formed between the first electrode and the switching element.
