An improved front assembly for a color cathode ray tube having a tension foil shadow mask is disclosed. The faceplate of the tube has on its inner surface a centrally disposed phosphor screen surrounded by a peripheral sealing area adapted to mate with a funnel. A shadow mask support structure secures a shadow mask in tension on the structure and spaces the shadow mask from the screen. The support structure is a generally L-shaped support member having one leg projecting from the faceplate and defining a ridge for securing the shadow mask to the support member. The other leg of the L-shaped support member projects along the screen for securing the support structure to the faceplate. Stiffening ribs span the legs of the support member. |
