Active matrix board having double-layer scan lines and capacity lines with discontinuous lower scan lines and lower capacity lines

An active matrix board comprising:

• a plurality of pixel electrodes disposed in a matrix fashion on an insulating substrate;
• a plurality of lower scan lines disposed on the insulating substrate in a parallel manner between the pixel electrodes, each lower scan line being formed from a low resistivity material and comprising a plurality of discontinuous segments, each segment corresponding to each pixel electrode;
• a plurality of upper scan lines disposed continuously over the lower scan lines, each upper scan line being formed from an anodizable metal and having a width wider than that of the lower scan line;
• a plurality of lower addition capacity lines disposed on the insulating substrate in a parallel manner between the pixel electrodes, each lower addition capacity line being formed from a lower resistivity material and comprising a plurality of discontinuous segments, each segment corresponding to each pixel electrode;
• a plurality of upper addition capacity lines disposed continuously over the lower addition capacity lines, each upper addition capacity line being formed from an anodizable metal and having a width wider than that of the lower addition capacity line;
• a plurality of anodized films formed by the anodization of the upper scan lines and the upper addition capacity lines;
• an insulating layer disposed over the anodized films;
• and
• a plurality of source lines disposed in a parallel manner so as to be perpendicular to the lower scan lines and the lower addition capacity lines, each source line being formed over the anodized film such that the discontinuity of the lower scan lines and lower addition capacity lines can prevent the upper lines from a breakdown caused by erosion spreading.
