Abstract
In an electro-optic device 1, connection to first electrodes 40 of a first transparent substrate 10 extending in one direction from the side, to which signals are inputted, is established through electrical conduction between two substrates in a width-wise central area of the first transparent substrate using first terminals 81. To second electrodes 50 of a second transparent substrate 20 which are routed toward the outer side, signals are directly inputted from second terminals 82. The obliquely routed second electrodes 50 are formed of, e.g., an aluminum alloy film, and slit-like openings are formed in the second electrodes 50 to allow passage of light emitted from a backlight device 9.
