A display assembly for a portable terminal inhibits the penetration of foreign matter from an exterior environment into the interior of the portable terminal. The display assembly includes a display for mounting in an open-faced compartment enclosed by a bottom/top cover plate. A resilient seal component of the display assembly is positioned between the display and the compartment, the seal component including a body including a base portion connected to a top portion by side portions for defining an interior channel for engaging the sides of the display, once received therein. A top portion of the seal component is adapted for overlapping a portion of the top surface of the display and the base portion for overlapping at least a portion of the bottom surface of the display.
