Display device with plate-like control electrodes |
摘要 |
A display device of the present invention reduces the occurrence of cracks and breaking of plate-like control electrodes, enhances the operability of assembling and suppresses the reduction of a yield factor of products. The display device includes a back substrate which has a plurality of cathode lines which extend in one direction, are arranged in parallel in another direction which crosses one direction and include electron sources respectively, and a plurality of control electrodes which cross the cathode lines in a non-contact manner within a display region, extend in another direction and are arranged in parallel in one direction on an inner surface thereof, and a front substrate which has anodes and phosphors on an inner surface thereof and faces the back substrate with a given distance therebetween. The control electrodes are formed of plate-like control electrodes. The plate-like control electrode includes electron passing holes which allow electrons emitted from the electron sources to pass therethrough in the display region. Further, the plate-like control electrode has a portion which is fixed to the back substrate in an external non-display region. Still further, the plate-like control electrode has at least a portion in the external non-display region where the strength of the plate-like control electrode is gradually changed toward an end portion thereof in the extending direction.
