Abstract

An electronic apparatus includes a display panel including a folding area foldable with respect to a folding axis and a non-folding area which is adjacent to the folding area, a support plate facing the display panel, and a digitizer which faces the display panel with the support plate therebetween and detects a first external input. The digitizer includes a plate including a reinforcing fiber, a first conductive layer on a first surface of the plate, and a second conductive layer on a second surface of the plate which is opposite to the first surface of the plate.
