Abstract
When a counter signal lineelectrically connected to a counter electrodeis provided on an active matrix substrate, a coilis formed by allowing a part of the counter signal lineto make a loop in a plane parallel to the substrate. To form the coil, two wiring layers provided to the active matrix substrateare used. By inserting the coilin series with the counter signal line, high-frequency noise placed on a counter electrode voltage is suppressed and a liquid crystal applied voltage is stabilized, improving the display quality of a liquid crystal screen. A similar coil may be formed using a power supply line on the active matrix substrate. By this, a liquid crystal panel which is highly immune to noise even without providing anti-noise components is provided.
