    • A spacer structure is provided between a first substrate formed with a phosphor screen and a second substrate provided with a plurality of electron emission sources. A supporting substrate of the spacer structure has a first surface opposed to the first substrate, a second surface opposed to the second substrate, and a plurality of electron beam apertures opposed to the electron emission sources. A plurality of spacers are set up on the second surface. The supporting substrate has a plurality of height reducing portions which are individually in contact with the spacers and elastically deformable in the height direction of the spacers. Each of the height reducing portions has a recess formed in the first surface so as to face the spacer and a plurality of grooves formed on the second surface and situated around the spacer.
    • 在形成有荧光屏的第一基板和设置有多个电子发射源的第二基板之间设置间隔结构。 间隔结构的支撑衬底具有与第一衬底相对的第一表面,与第二衬底相对的第二表面和与电子发射源相对的多个电子束孔。 多个间隔件设置在第二表面上。 支撑基板具有多个高度减小部分,该多个高度减小部分分别与间隔件接触并可在间隔件的高度方向上弹性变形。 每个高度减小部分具有形成在第一表面中以与面对间隔件的凹部和形成在第二表面上并且位于间隔件周围的多个凹槽。
