Abstract
An auxiliary line including a guide layer and an auxiliary metallic member is formed with respect to a signal transmitting line or a main auxiliary capacitance line formed on a glass substrate. The guide layer is formed in the same layer where pixel electrodes are formed. The auxiliary metallic member is formed by using a method such as an inkjet method, in which fine particles of metal is ejected or dropped.
Claims38
An active matrix substrate, comprising:
- a substrate;
- a plurality of signal lines;
- a plurality of scanning lines intersecting with the signal lines;
- switching elements, each being arranged nearby a portion where one of the signal lines intersects with one of the scanning lines;
- a peripheral line having at least a function of supplying signals to the signal lines and the scanning lines, the signal lines, the scanning lines, the switching elements, and the peripheral line being provided on the substrate;
- and
- the active matrix substrate further comprising:
- a protection layer formed on the substrate;
- a resin layer formed on the protection layer;
- a groove configured in the protection layer and the resin layer or configured in the substrate;
- and a conductive auxiliary member filled in the groove and in continuous longitudinal contact along a substantial length of one of said signal lines, said scanning lines or said peripheral line on said active matrix substrate so as to lower a combined resistance value of the conductive auxiliary member and one of the signal lines, said scanning lines or said peripheral line.
