ACTIVE MATRIX TYPE DISPLAY DEVICE

Japanese Patent JP3307150

B2

PURPOSE: To impart an electric shielding function and electric contact function to light shielding films formed on a driving substrate side.
CONSTITUTION: This active matrix type display device includes a driving substrate 1 having pixels 4, a counter substrate 2 having counter electrodes 5 and liquid crystals 3 held in a spacing between both. The upper layer part of this driving substrate 1 includes pixel electrodes 6 formed at every pixel 4. The lower layer part includes thin-film transistors (TFTs) 7 for driving the individual pixel electrodes 6, scanning wirings 8 and signal wirings 9. Light shielding films having electrical conductivity are interposed between the upper layer part and the lower layer part and are separated to the mask light shielding films 16M and pad light shielding films 16P. The mask light shielding films 16M are continuously patterned along the row direction of the pixels 4 to at least partly shield the light of the TFTs 7, are insulated from the upper layer part and lower layer part and are held at fixed potential. The pad light shielding films 16P are discretely patterned for every pixel 4 and are interposed into the contact parts C between the corresponding pixel electrodes 6 and the TFTs 7, thereby providing the electrical connection and light shielding thereof.
