A liquid crystal aligning agent capable of forming a liquid crystal alignment film having favorable electrical characteristics, and excellent in the storage stability and the productivity. A first secure storage location is operably decoupled from all of the external outputs of the SOC device during a normal mode of operation. Ideally, each mode of operation is activated and deactivated independent of the other modes, although two or more modes may be concurrently operational. A local printing system equipped with a print head that dispenses the selected material is used to print. The memory controller distributes the data to either the first storage section or the second storage section depending on the data property. The photoelectric converter has a sufficiently high SN ratio and can be produced at low cost.
