摘要:
An electromagnetic device and a high-voltage generating device which are thin and improved in the characteristics are provided in which a magnetic core is made of a cylindrical form of a ferrite material having a higher intrinsic resistance. A winding is provided by winding a flat rectangular wire conductor in an edge-wise winding form directly on substantially the entire length of the magnetic core. As any insulator such as a coil bobbin is not needed between the flat rectangular wire conductor and the magnetic core, the winding can be decreased in the overall size or thickness thus contributing to the dimensional reduction of the electromagnetic device. Also, as its flat rectangular wire conductor is wound directly on the magnetic core, the winding can be minimized in the length and thus the overall resistance. Moreover, as there is no gap between the winding and the magnetic core, the self-inductance can be reduced while the size and the number of turns of the winding remain unchanged.

A liquid crystal device includes a pair of substrates that face each other, a liquid crystal layer that is interposed between the pair of substrates, electrodes that are formed on opposing surfaces of the pair of substrates so as form a plurality of subpixel regions, in each of which a reflective display region having a light-reflective film reflecting light and a transmissive display region transmitting light are provided, and an insulating layer that is formed between one of the pair of substrates and the liquid crystal layer such that a thickness of the liquid crystal layer in the reflective display region is smaller than a thickness of the liquid crystal layer in the transmissive display region. The insulating layer is formed to have a first film thickness in the reflective display region, and is provided between the transmissive display region of a predetermined subpixel region and the transmissive display region of a subpixel region adjacent to the predetermined subpixel region. A portion of the insulating layer is formed to have a film thickness smaller than the first film thickness between the transmissive display region of the predetermined subpixel region and the transmissive display region of the subpixel region adjacent to the predetermined subpixel region.

摘要:
A first shading region for defining a display region is arranged on a light-transmitting substrate. A cell thickness adjustment layer is arranged on the substrate inside the display region and a second shading region for defining a boundary of a plurality of pixel regions is arranged on the cell thickness adjustment layer. The cell thickness adjustment layer is selected so that the total thickness of the second shading region is not smaller than the total thickness of the first shading region. The cell gap can thus be made uniform throughout the whole display region and non-uniformity of display can be prevented.
