Abstract

An image display apparatus according to the present invention includes a housing, a front frame provided forward of the housing, and a display assembly accommodated in the housing. The display assembly includes a display and a transparent plate provided forward of the display. The transparent plate is larger in outer dimension than the display and has a flange portion extending outward with respect to an outer edge of the display. A seal member is interposed between the flange portion and an outer peripheral portion of the housing. When the housing and the front frame are fastened to each other, a front surface of the flange portion of the transparent plate is brought into pressure contact with a rear surface of the front frame, and the seal member is sandwiched between the front frame and the housing with a pressure applied thereto.

Claims

1. An image display apparatus comprising:

a housing having an open front and including a chamber formed therein;

a front frame provided forward of the housing;

a display assembly accommodated in the chamber of the housing, and including a display and a transparent plate fixed directly to a front surface of the display by bonding, wherein the transparent plate is larger in outer dimension than the display and has a flange portion extending outward with respect to an outer edge of the display; and

,

an elastic seal member extending around the chamber is interposed between the flange portion of the transparent plate and an outer peripheral portion of the housing, the outer peripheral portion of the housing being formed on a surface thereof opposed to the front frame with a groove for fitting the elastic seal member thereinto,

wherein, when the housing and the front frame are fastened to each other, a front surface of the flange portion of the transparent plate is brought into pressure contact with a rear surface of the front frame, and when the seal member is sandwiched between the front frame and the housing with a pressure applied thereto to become deformed elastically, an inner wall of the groove serves to restrain the deformation of the elastic seal member to control the shape and amount to be deformed.

2. The image display apparatus according to claim 1, wherein a double-sided adhesive tape for fixing the seal member is applied onto the groove of the housing.

3. The image display apparatus according to claim 2, wherein the front frame has plural ribs formed to protrude from a surface thereof opposed to the housing.

4. The image display apparatus according to claim 3, wherein the plurality of reinforcing ribs include a horizontal reinforcing rib and a vertical reinforcing rib which intersect each other.
