Semi-transmission LCD device and method of making the same

A substrate for a liquid crystal display device, the substrate having a reflecting area and a transmitting area and including:

• an insulating substrate;
• a polysilicon layer disposed at the insulating substrate and having a channel area, a source area and a drain area, the source area and the drain area being separated from each other by the channel area;
• a gate wiring comprising a gate electrode positioned on the channel area;
• data wiring comprising a source electrode and a drain electrode electrically connected to the source area and the drain area, respectively;
• an organic layer disposed at the data wiring;
• a reflecting layer disposed at the organic layer and defining the reflecting area;
• a color filter layer disposed at the reflecting layer;
• and
• a pixel electrode layer disposed at the color filter layer and electrically connected to the drain electrode.

A method of making a liquid crystal display device comprising a first substrate having a reflecting area and a transmitting area and a second substrate opposing to the first substrate, the method comprising:

• forming a polysilicon layer having a channel area, a source area and a drain area on a first insulating substrate of the first substrate, the source area and the drain area being separated from each other by the channel area;
• forming a gate wiring comprising a gate electrode disposed corresponding to the channel area;
• forming a data wiring comprising a source electrode and a drain electrode electrically connected with the source area and the drain area, respectively;
• forming an organic layer on the data wiring;
• forming a reflecting layer on the organic layer, the reflecting layer defining the reflecting area;
• forming a color filter layer on the reflecting layer;
• forming a pixel electrode layer on the color filter layer, the pixel electrode layer being electrically connected with the drain electrode;
• and
• forming a common electrode layer on a second insulating substrate of the second substrate.
