Abstract
When a counter signal line 13 electrically connected to a counter electrode 24 is provided on an active matrix substrate 11 , a coil 14 is formed by allowing a part of the counter signal line 13 to make a loop in a plane parallel to the substrate. To form the coil 14 , two wiring layers provided to the active matrix substrate 11 are used. By inserting the coil 14 in series with the counter signal line 13 , 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 11. By this, a liquid crystal panel which is highly immune to noise even without providing anti-noise components is provided.
Claims8
A liquid crystal panel having a structure in which a liquid crystal is sandwiched between a pair of substrates, the liquid crystal panel comprising:
- an active matrix substrate having a plurality of pixel circuits formed on a glass substrate, each pixel circuit including a switching element and a pixel electrode;
- and
- a counter substrate having a counter electrode formed on another glass substrate, the counter electrode facing the pixel electrodes, wherein
- the active matrix substrate includes a coil formed by allowing a part of at least one of a counter signal line electrically connected to the counter electrode and a power supply line on the substrate to make a loop in a plane parallel to the substrate.
