Patent ID: 8879244

Claim:
A display device comprising: a front plate having a transparent board and a mounting frame, the mounting frame having a bottom attached to a back face of the transparent board and a side perpendicular to the bottom and a long hole in the side; a display panel disposed on a back face side of the front plate; and a mounting member having a fixed section fixed to a back face of the display panel and a locking section extending from the fixed section and loosely inserted into the long hole of the mounting frame to be movable in a longitudinal direction of the long hole which is parallel to an X-axis and in a direction passing through the long hole and perpendicular thereto and which is parallel to a Y-axis and non-movable in a front-back direction which is perpendicular to a display surface of the display panel and which is parallel to a Z-axis, in which the X-axis, the Y-axis and the Z-axis are orthogonal to each other, the locking section having a first portion, a second portion and a third portion arranged such that the first portion extends from the fixed section at a slant to the second portion which extends along the side of the mounting frame to the third portion which is bent so as to be substantially parallel to the fixed section and insertable into the long hole of the mounting frame, and the third portion of the locking section being (i) movable in the long hole in the longitudinal direction which is parallel to the X-axis and in the perpendicular direction thereto which is parallel to the Y-axis to enable movement due to thermal contraction differences in the directions parallel to the X-axis and the Y-axis, and (ii) non-movable in the front-back direction which is parallel to the Z-axis to cause the front plate and the display panel to be fixed together and non-movable in the front-back direction.
