Liquid crystal display device and method for fabricating the same

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;
• and
• (iii) a first electrode having a transparent electrode, said transparent electrode which has a portion thereof connected with said output so as to apply a first electric power and a rest portion thereof covering said projection, and a reflection electrode supplied with electric power from said transparent electrode, said reflection electrode which has a portion thereof opened to transmit a first light and a rest portion thereof covering said transparent electrode formed on said projection to change a reflection factor of a second light passing in a different direction from said first light 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.

A method for fabricating a liquid crystal display device, the method comprising the steps of:

• forming a first substrate by (i) forming a plurality of thin film transistors arranged in a matrix shape;
• (ii) forming 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;
• and (iii) forming a first electrode formed on said organic insulating layer, said first electrode having a portion that is connected with said output so as to receive a first electric power, and said first electrode having a rest portion that covers said projection to have various reflection factors depending on an observation angle and formed in a matrix shape;
• forming a second substrate including i) a color filter disposed opposite to the first electrode and ii) a second electrode covering the color filter;
• and
• interposing a liquid crystal between the first substrate and the second substrate.
