A display apparatus has a cathode ray tube bulb which includes a panel displaying
a picture thereon, a funnel combined with the panel, and a neck connected to the
funnel. The display apparatus further comprises an electron gun unit which includes
an electron gun main body inserted into the neck and a boss part protruding from
the neck at a rear part of the electron gun main body and having a plurality of
pins disposed therearound, and a video unit which includes a video PCB disposed
parallel to the axis of the neck and a boss holder vertically provided on the video
PCB and combined with the boss part so as to transmit a video signal from the video
PCB to the electron gun unit. With this configuration, space for installation of
the video PCB is minimized, and the video unit is not easily separated from an
electron gun unit.
