Abstract:
A liquid crystal display device, comprising:a first substrate on which a pixel transistor formed of a semiconductor layer, and a light shielding film for shielding against incident light or scattered light are formed, wherein a portion of said light shielding film except its portion for shielding said pixel transistor is disposed beneath an additional capacitance line at a position avoiding said gate line, said light shielding film being connected to a potential so that an increase in parasitic capacitance between the light shielding film and the gate line is suppressed, a load amount on the gate line is suppressed, and a delay of gate potential is small;said first semiconductive layer being located beneath the capacitance line and spaced from the lights shielding film by a gate insulating film and substantially in register with the light shielding film at a location not beneath the gate line;a second substrate disposed opposite to said first substrate and with a predetermined interval; anda liquid crystal layer held between said first substrate and said second substrate.
