Abstract:
1. A substrate for an electro-optical device comprising: a metal layer provided over a substrate; a plurality of layers laminated over the metal layer; a first layer initially formed in the plurality of layers, the first layer covering an outer periphery of the metal layer and extending beyond the outer periphery of the metal layer by a first distance; a first insulating layer laminated over the plurality of layers, the first insulating layer covering an outer periphery of the first layer and extending beyond the outer periphery of the first layer by a second distance; and a second insulating layer laminated over the first insulating layer, the second insulating layer covering an outer periphery of the first insulating layer and extending beyond the outer periphery of the first insulating layer by a third distance, wherein the plurality of layers are formed so that the outer periphery of the first layer is arranged most outside in the plurality of layers; the second distance is longer than the first distance and the third distance is longer than the second distance; and the first layer is colored.
