ABSTRACT:
A large area display has a plurality of cathode ray tubes mounted adjacent each other in X, Y matrix and each cathode ray tube includes a plurality of pixels arranged in an X, Y matrix on a front panel and each pixel comprises three horizontally extending stripe-shaped luminous elements aligned in the vertical direction and the front panel of the cathode ray tube is formed with a thinner portion adjacent its outer edge where it joins to the funnel to reduce the spacing between adjacent cathode ray tubes to a minimum to allow the pixels to be viewed over a wider angle.
