    • A gap formed between cathode wires 2 (electron emitting sources 2a) and control electrodes 4 is made uniform and a gap formed between a rear panel 100 and a face panel 200 is held at a predetermined value with high accuracy. Plate-like members are used as the control electrodes 4. Holes 4a which allow electrons emitted from the electron emitting sources 2a provided to the cathode wires 2 to pass through the control electrodes 4 toward the face panel 200 side are formed in pixel regions which are defined by the cathode wires 2 and the control electrodes 4 crossing the cathode wires 2 both of which are formed on the rear panel 100. Contact portions 10 which are projected toward the rear panel 100 side and support the control electrodes 4 are provided between the neighboring cathode wires 2. Further, gap holding members 9 which hold the gap between the face panel 200 and the rear panel 100 at the predetermined value are provided right above the contact portions 10 and at the face panel 200 side.
    • 阴极线2(电子发射源2a)和控制电极4之间形成的间隙均匀,并且在后面板100和面板200之间形成的间隙以高精度保持在预定值。 板状构件用作控制电极4.允许从设置到阴极线2的电子发射源2a发射的电子通过控制电极4朝向面板200侧的孔4a形成在像素区域 由阴极线2和与阴极线2交叉的控制电极4两者形成,两者均形成在后面板100上。朝向后面板100侧突出并支撑控制电极4的接触部分10设置在相邻 此外,将面板200和后面板100之间的间隙保持在预定值的间隙保持构件9设置在接触部分10正上方和面板200侧。
