A color filter substrate includes first and second layers having openings, a filter layer located in the openings, a reflecting component, and a transmitting component. The reflecting component is provided at least partially on a second side of the filter layer such that first light rays that are incident on the filter layer from a first side are reflected to the first side, where the first side is an opposite side of the second side. The transmitting component is provided at least partially on the second side of the filter layer, such that second light rays that are incident on the filter layer from the second side are emitted to the first side. The present invention provides a color filter substrate, a liquid crystal display device, and an electronic device having a structure that allows good coating with a liquid material.
