Patent ID: 8907881

Claim:
A liquid crystal display device comprising a plurality of pixels, at least one of the plurality of pixels comprising: a first signal line, a second signal line, and a third signal line; a first scan line, a second scan line, and a third scan line; a first transistor, a second transistor, and a third transistor; and a liquid crystal element, wherein a gate of the first transistor is electrically connected to the first scan line, a first terminal of the first transistor is electrically connected to the first signal line without passing through a semiconductor, and a second terminal of the first transistor is electrically connected to a first electrode of the liquid crystal element, a second terminal of the second transistor, and a second terminal of the third transistor, wherein a gate of the second transistor is electrically connected to the second scan line and a first terminal of the second transistor is electrically connected to the second signal line without passing through the semiconductor, wherein a gate of the third transistor is electrically connected to the third scan line and a first terminal of the third transistor is electrically connected to the third signal line without passing through the semiconductor, and wherein each of the first to third transistors comprises a semiconductor layer which comprises a polycrystalline semiconductor or a single crystal semiconductor.
