Abstract:
An electro-optical device comprising:a first substrate having an alignment layer that has been subjected to a rubbing process, a second substrate, opposed to the first substrate and having an alignment layer that has been subjected to a rubbing process, an electro-optical material interposed between the first substrate and the second substrate, a step portion, formed in the surface of the alignment layer of at least one of the first substrate and the second substrate, and downwardly rubbed in the direction of the rubbing process, and a light shield layer formed in an area facing the step portion that is downwardly rubbed in the direction of the rubbing process, on at least one of the first substrate and the second substrate, wherein 0.5D1 and d1+300 nmwherein D is a thickness of the electro-optical material between the first substrate and the second substrate, except the step portion, W1 is a spacing between adjacent pixel electrodes, and d1 is a thickness of the electro-optical material at the step portion between the first substrate and the second substrate.
