    摘要: Light radiated from a light source 1 is gathered by an oval mirror 2. The gathered light is incident on one end of a rod-shaped optical integrator 3, integrated and made uniform within the optical integrator 3, and is radiated from the other end of the optical integrator 3. The light 10 from the optical integrator is diffused and projected on an exposure area 6a of a display tube by a lens system 7. The lens system 7 presents astigmatism, thereby forming a first virtual focus and a second virtual focus on its virtual image area. The diffused light is apparently diffused vertically at the first virtual focus and diffused horizontally at the second virtual focus. The foregoing first vertical focus and second vertical focus correspond in position to the positions of the vertical deflection means and horizontal deflection means of this display tube.
    Therefore, the directions of the exposure light beams to shed light on G, B and R dots are in agreement with the directions of the deflected electron beams.
    As a result, the above deflected electron beans can sweep over the G, B and R dots accurately in synchronization with image signals.

    摘要: The present invention relates to a color cathode ray tube that reduces a leakage electric field and a maximum instantaneous current generated in a bulb at the time of electric discharge and provides a stable connection of conductive layers with different specific resistance. A first conductive layer (24) is formed on the entire area of an inner wall (22) of a funnel (26) including a contact portion of a first spring (31) supported by a shadow mask structure (29), an anode button (25) and a contact portion of a second spring (32) supported by a final electrode of an electron gun. A second conductive layer (33) with a specific resistance lower than that of the first conductive layer is formed on the surface of the first conductive layer within the range extending from the anode button to the contact portion (31a) of the first spring. The contact portion of the first spring contacts the second conductive layer, thereby electrically connecting the shadow mask structure to the second conductive layer, and the contact portion of the second spring contacts the first conductive layer, thereby electrically connecting the final electrode (30a) to the first conductive layer.
