Abstract
In a display device including a display panel and a multi-layered printed circuit board which is arranged along one side of the display panel and is electrically connected to a plurality of leads of the display panel through a plurality of tape carrier packages, according to the present invention, a plurality of slits or notches are formed in a sheet fiber member which is impregnated with resin and constitutes a base sheet of the multi-layered printed circuit board along one side of the display panel. The discontinuity of the sheet fiber member formed by the slits or the notches absorbs the difference in thermal expansion of the multi-layered printed circuit board and the display panel due to the change of an ambient temperature of the display device and hence, it is possible to prevent peeling of the tape carrier package from the display panel or breaking of the tape carrier package per se.
