A small-sized, simple and inexpensive electronic part protecting structure and process enabled to prevent the reconstruction of electronic parts by preventing a case from being opened. Into a plurality of through holes formed in the surface of one case, there are loosely fitted projecting pieces which are provided on the surface of the other case. The projecting pieces are provided at their leading ends with deformed portions which are made so larger than the through holes that they can not be restored. By these deformed portions, the cases cannot be easily opened to prevent the electronic parts protected between the cases from being easily extracted while preventing the reconstruction. The case having the projecting pieces is made of a metal or resin. The through holes are formed in recesses of the case surface. The cut-off the deformed portions is detected and reported. Into the through holes formed in the surface and back protecting cases, on the other hand, there is inserted a protecting pin member. This protecting pin member has a flat portion at its one end, and a deformed portion is formed at the other end after the protecting pin member was inserted. The flat portion and the deformed portion are made so larger than the through holes that they can not be restored. As a result, the cases cannot be easily opened to prevent the easy extraction of the electronic parts protected therebetween and to prevent the reconstruction.

Electronic part protecting structure having deformable pins

A signal input electrode portion formed on a liquid crystal display panel which has driver LSIs outputting signals for driving picture elements is detachably inserted from a side direction thereof into and is connected to a connector mounted on a circuit board for supplying electric power and input signals to the liquid crystal display panel. The liquid crystal display panel is electrically connected with the circuit board through the connector.

Liquid crystal display device having light guiding plate disposed

A liquid crystal display device comprises an edge light type of a light guide plate for a backlight, having an inclined surface. A back light lamp disposed in a side of a wide edge surface of the light guide plate. A liquid crystal display panel disposed in a side of a rear surface of the light guide plate. A circuit board disposed at a recess of the inclined surface of the light guide plate. A tape carrier connecting the liquid crystal display panel and said circuit board with each other. And an integrated circuit disposed on the tape carrier for driving the liquid crystal panel.
