ABSTRACT:
A metallic frame for use in a fluorescent display panel having a CIG (chip in glass) structure and containing a driver IC chip in a vacuum chamber. The metallic frame includes a box-type metallic shield covering the IC chip, metallic external leads, and a deformable part coupled between the box-type metallic shield and the metallic external leads. The deformable part deforms more easily than the metallic shield and the leads upon receiving a tensile force. The deformable part is preferably formed at a bent section of the metallic shield or near a shield side end of the metallic external leads. The deformable part preferably consists of two bent or curved elements which are positioned to form a circle, ellipse, or polygon.
