摘要： A method is directed towards fabricating a printed circuit board (PCB) having a thin core layer. In the method, a substrate, where a copper foil is formed on a release film and a prepreg, is employed as a base substrate and a core insulating layer is removed after the fabrication of the PCB, thereby reducing the thickness of the final product.

摘要： A backlight unit of an LCD device is disclosed in which a light-diffusion substance below a light-guiding plate is formed as one body with a reflecting sheet by using a photonic crystal reflecting sheet to improve color purity. The backlight unit includes a lamp; a photonic crystal reflecting sheet having a plurality of parts; and a plurality of sheets formed above the photonic crystal reflecting sheet. Each part of the photonic crystal reflecting sheet includes a photonic crystal for selectively reflecting the light of a predetermined wavelength in the light emitted from the lamp. The wavelengths are different, thereby permitting the photonic crystal to reflect different colors in different areas.
