Color filter substrate, electro-optic device, and electronic apparatus

A color filter substrate comprising:

• a light-transmissive substrate including an incident surface and an outgoing surface with respect to transmitted light;
• a plurality of pixels in which a color filter layer is formed;
• a protrusion portion that is disposed between the plurality of pixels on the outgoing surface of the light-transmissive substrate and partitions the color filter layer, the protrusion portion including:
• a light-transmissive layer comprising a light transmissive material that forms a reflective side surface, the reflective side surface being formed as an inclined surface and partitioning the color filter layer into at least a first color filter having a first color and a second color filter having a second color filter, the first color filter being directly adjacent to the second color filter;
• and
• a light-shielding layer disposed such that the light-transmissive layer is disposed between the light-transmissive substrate and the light-shielding layer,
• wherein
• the light-transmissive layer is disposed between at least the first color filter and the second color filter,
• the light-transmissive layer disposed between the first color filter and the second color filter includes both a first strip-shaped light-transmissive layer and a second strip-shaped light-transmissive layer parallel to the first strip-shaped light-transmissive layer,
• the first strip-shaped light-transmissive layer has a first side surface facing the first color filter and a second side surface facing the second strip-shaped light-transmissive layer, and
• the second strip-shaped light-transmissive layer has a first side surface facing the second color filter and a second side surface facing the first strip-shaped light-transmissive layer.
