An object of the present invention is to provide a liquid crystal display apparatus that can eliminate brightness nonuniformity by suitably diffusing light emitted from a light source. The liquid crystal display apparatus includes a liquid crystal panel providing a liquid crystal between a pair of substrates, the liquid crystal panel having an effective display area for displaying information, a sealing member placed around the liquid crystal in order to seal the liquid crystal between the pair of substrates, a light source for illuminating the liquid crystal panel from an edge thereof, and light diffusing means, provided between the pair of substrates, for diffusing the light introduced from the light source into the effective display area.

Liquid crystal display device

Semiconductor packages which are prepared by forming circuit substrates, mounting IC chips on the circuit substrates, encapsulating the IC chips on the circuit substrates with resin, and forming electrodes, are attached to a standard member. After this attaching step, the semiconductor packages are subjected to a cutting step where the semiconductor packages are diced into a plurality of circuit substrates.

Process for manufacturing semiconductor package and circuit board assembly

An organic resin film,having an opening on an electrode pad is formed on a main surface of an IC chip,and a protruding electrode,formed on the electrode pad is formed of a low melting point eutectic solder. As a result, the protruding electrode,is formed without melting the organic resin film while preventing a crack from being generated by a stress applied between the electrode pad and the IC chip. Thus, the reliability of a semiconductor package can be enhanced.
