Abstract
A liquid crystal display apparatus in which an arrangement possibly susceptible to degradation in display quality by a miss shot of a laser used for turning amorphous silicon into polycrystalline silicon is avoided and a narrow peripheral frame can be attained. A gate interconnection for transistors in a driving circuit area is arranged along a folded line having two lines extending in two different directions and a bent portion. Channel regions of the transistors are arranged along the two lines, such that the channel regions do not overlap the bent portion.
Claims8
A liquid crystal display apparatus including:
- a liquid crystal display;
- and
- a thin film transistor (TFT) panel, for driving the liquid crystal display, having a display area and, on at least one side of said display area, a driving circuit area on which a plurality of driving transistors are located, said driving transistors including respective sources, gates, drains, and channel regions electrically connecting respective sources and drains, and said driving circuit area including gate interconnections interconnecting gates of at least pairs of said driving transistors, wherein
- said gate interconnections are located along respective zigzag patterns, each zigzag pattern including a first straight line extending along a first direction, a second straight line extending along a second direction different from the first direction, and a third straight line intersecting and oblique to each of the first and second straight lines, and
- said gates of said driving transistors that are interconnected are located on the first and second straight lines, and said channel regions of said driving transistors do not overlie the third straight line.
