<P>PROBLEM TO BE SOLVED: To prevent a linear defect and a surface detect in a semitransmissive reflection type optoelectronic device, even if a transparent electrode and a metal reflecting film are electrically connected to each other in some pixel region. <P>SOLUTION: In the optoelectronic device such as a liquid crystal display device, metal reflecting films corresponding to a reflective region are formed on a transparent substrate and an insulating layer is formed so as to surround each of the reflecting films, made of a metal such as aluminum, around the metal reflecting films. A color filter layer is formed so as to cover the reflecting films. Therefore, in each pixel region, the reflecting film is provided in the insulating layer in an island shape so as to be separated from adjacent reflecting films and isolated form circumferential reflecting film, thereby limiting influences to only the pixel region even if the color filter layer has a defect such as a pinhole or conductive foreign matter such as metal is mixed to electrically connect the reflecting film and transparent electrode to each other. Consequently, a linear defect or surface defect is prevented to improve the yield of the optoelectronic device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
