Liquid crystal panel substrate with light-shielding film in a pixel region, liquid crystal panel, and electronic equipment and projection type display device both using the same to reduce light leakage

A substrate for a display device, comprising:

• a plurality of electrodes that are formed in a pixel region, each of the plurality of electrodes being positioned at a first position corresponding to one pixel of a plurality of pixels;
• a plurality of first switching elements that are formed in the pixel region, each of the plurality of first switching elements being positioned at a second position corresponding to one pixel of the plurality of pixels;
• a metal layer that overlaps at least a part of one first switching element of the plurality of first switching elements;
• a driving circuit that is positioned outside of the pixel region, the driving circuit including a plurality of second switching elements;
• and
• a wire that is positioned in the driving circuit, the wire being electrically connected to one second switching element of the plurality of second switching elements.
