Providing a display apparatus with a structure suitable to support a
ring-shaped member for three-dimensional effect to express information
for recognition of a partial area of a display area of a display unit by
surrounding the partial area with the ring-shaped member arranged in
front of the display area so as to be movable linearly along the display
area, the ring-shaped member is supported at the top side and the bottom
side of the rear edge in a top-bottom direction along the display area
and perpendicular to a direction of the linear motion, by each mount
piece of the supporting member. Front portions of the mount pieces
located in front of the display area are completely covered by the facing
plate located between the front portions and the front large diameter
portion of the ring-shaped member.
