Patent ID: 7580096

Claim:
A liquid crystal display device comprising: a first substrate including: (i) a plurality of thin film transistors arranged in a matrix shape; (ii) an organic insulating layer insulating said thin film transistors from each other, said organic insulating layer having a contact hole exposing an output of each of said thin film transistors and a projection that has at least one irregular reflection surface to selectively control light reflection, wherein a slope of a first tangent of a curve in a first direction of said projection is higher than a slope of a second tangent of a curve in a second direction of said projection; (iii) a plurality of first electrodes formed in a matrix shape on said organic insulating layer, each of said first electrodes having a portion that is connected with said output so as to receive a first electric power, and a rest portion that covers said projection, each said rest portion having an opening formed through each of said first electrodes corresponding to a display area to have various reflection factors depending on an observation angle; and (iv) a viewing-angle varying section between the first electrodes, the viewing-angle varying section having a curved surface protruding from the organic insulating layer and having a symmetrical shape, and the rest portion of each of said plurality of first electrodes disposed at both sides of said viewing-angle varying section asymmetrically extends onto the curved surface of said viewing-angle varying section, to thereby change the reflection factor depending on an observation angle; a second substrate including i) a color filter disposed opposite to said first electrode and ii) a second electrode covering said color filter; and a liquid crystal interposed between said first substrate and said second substrate.
