Abstract
The present invention provides a display device which can sufficiently ensure spaces for mounting distance holding memberswhen the distance holding membersare mounted, can facilitate the assembling and can realize the electron emission characteristics of high performance. At least two different types of gaps b, c (b<c) are provided among cathode lines(R,G,B) and the distance holding membersare mounted at portions of the gaps c having a larger size whereby the space for mounting the distance holding memberscan be sufficiently ensured.
