The present invention relates to biocide batches based on cross-linked native oils, which are used to provide thermoplastic molding compositions with protection against insects and bacterial and fungal attack. A flat display panel is fixedly supported by an X-character shaped supporting member via dampers fitted in the four corners of the flat display panel by the flat panel fixing parts of the supporting member. The sealing layers are formed of a crystallized glass paste and an amorphous glass paste. Semiconductor chips are then disposed on the first face and are electrically connected with the circuit patterns respectively.
