ABSTRACT:
A CRT display device having a cathode ray tube for displaying an image, includes a front case having plural fixing bosses for mounting the cathode ray tube therein and four sides defining a display area; a deflection preventing rib, formed on each side of the front case, for minimizing a gap between the cathode ray tube and the front case; and a CRT chassis for fixing the cathode ray tube to the fixing bosses. Each deflection rib is made up of a first portion for receiving a pressing force from the installation of the cathode ray tube and a second portion for generating a reaction force against the front surface of the cathode ray tube. The first and second portions forming a profile comparable to the outer surface of the cathode ray tube.
