Abstract
In an electro-optical device, such as a transflective liquid crystal device, color transmissive display having normal color tones is performed, and in addition, bright, color reflection display is also performed. The electro-optical device in accordance with the invention includes an electro-optical material provided between a first substrate and a second substrate, and display electrodes provided above the first substrate so as to be opposed to the second substrate. The electro-optical device further includes a first color filter having a selective-reflection region in each pixel that selectively reflects light in a predetermined wavelength range, and a light transmission region in each pixel that transmits light outside of the predetermined wavelength range; a light-shielding film provided so as to be opposed to the selective-reflection regions; and a second color filter having a selective-transmission region in each pixel that selectively transmits light in the predetermined wavelength range.
