Liquid crystal display device and method of fabricating the same

A liquid crystal display device, comprising:

• a substrate;
• a first metal layer disposed on the substrate, the first metal layer includes a gate line connected to a gate electrode, and a first capacitor electrode;
• an insulating layer covering the first metal layer;
• a silicon layer disposed on the insulating layer, a portion of the silicon layer includes an active layer disposed over the gate electrode;
• a second metal layer disposed on the silicon layer, the second metal layer includes a data line, a source electrode, a drain electrode, and a second capacitor electrode;
• a passivation layer covering the second metal layer, a side edge portion of the drain electrode being exposed from the passivation layer;
• and
• a pixel electrode disposed on the passivation layer, the pixel electrode contacting the side edge portion of the drain electrode.

A halftone mask, comprising:

• a light shielding portion shielding a photoresist from incident rays of light;
• a semi-transmissive portion transmitting at least a portion of the incident rays of light to the photoresist;
• and
• a light transmissive portion transmitting at least all the incident rays of light to the photoresist.
