Device substrate, production method therefor, electronic device, production method therefor, optic device, production method therefor, and electronic apparatus

摘要

Object To provide a device substrate and a production method therefor, which device substrate has a film having a reflection function and can be formed by a production process that does not require a vacuum process inviting increased production cost. ;Solving Means A device substrate according to the present invention includes a substrate 1, an electronic element 2 mounted above the substrate 1, and a film 3 having a phase separation structure and arranged above the electronic element 2 so as to cover at least a part of the substrate 1 or the electronic element 2. Alternatively, the film 3 having a phase separation structure in the above configuration may be arranged below the electronic element 2. The film 3 having a phase separation structure can be arranged so as not come in contact with the substrate 1.
