A liquid crystal panel comprising:

• a substrate including a pixel region and a driver circuit region;
• a plurality of light shielding portions over the substrate in portions of the pixel region and the driver circuit region;
• a buffer layer over the substrate and the plurality of light shielding portions;
• complementary metal oxide semiconductor thin film transistors in the driver circuit region, the complementary metal oxide semiconductor thin film transistors including a first thin film transistor and a second thin film transistor, the first thin film transistor including first impurity regions of a first conductivity type;
• a channel layer, a gate insulating layer, and a gate electrode, the second thin film transistor including second impurity regions of a second conductivity type, a channel layer, a gate insulating layer, and a gate electrode;
• a third transistor in the pixel region, the third transistor including third impurity regions of said first conductivity type, fourth impurity regions of said first conductivity type, a channel layer, a gate insulating layer, and a gate electrode;
• an insulating layer on said pixel and drive circuit regions and having a contact hole over a portion of said pixel region;
• and
• a pixel electrode on the insulating layer and into the contact hole.
