- a heat treatment baking
- the metal film of the metal back layer 2 is dissolved or increased in resistance by the metal dissolving component contained in the liquid or the paste, and is electrically divided.
- the coating layer 12 derived from the paste application layer is formed. Since the coating layer 12 contains heat-resistant fine particles as a main component, fine irregularities corresponding to the diameter of the heat-resistant fine particles are formed on the surface of the coating layer 12.
- a getter material is vapor-deposited on the coating layer 12 containing the heat-resistant fine particles and having the unevenness on the surface. Then, only in the region where the coating layer 12 is not formed, the vapor deposition layer of the getter material is formed on the film, and as a result, the film-like getter layer 13 having a pattern that is inverted with respect to the pattern of the coating layer 12 is formed.

- the getter material a metal selected from Ti, Zr, Hf, V, Nb, Ta, W, Ba, or An alloy containing at least one of these metals as a main component can be used.

Therefore, after forming a pattern of the coating layer 12 containing heat-resistant fine particles and the like on the metal back layer 2, the phosphor screen 1 is disposed in the vacuum envelope by assembling the vacuum envelope, and the vacuum screen is enclosed. It is desirable to perform a getter material deposition process in the vessel.

- the metal film is dissolved / removed or the resistance is increased, and the electrical separation part 11 is formed in the metal back layer 2, and the coating layer 12 formed in the separation part 11 forms a vapor deposition on the metal back layer 2. Since the obtained film-like getter layer 13 is divided, good withstand voltage characteristics are ensured without formation of the getter layer 13 impairing the dividing effect of the metal back layer 2.
- the surface resistance of the light absorption layer 9 located below the division 11 is controlled to a predetermined value, and the divided metal back layer 2 is electrically connected with this resistance. As a result, the pressure resistance is further improved.
- a desired breakdown voltage characteristic can be obtained only by forming the covering layer 12 having a single structure, so that the number of steps is reduced, the production efficiency is greatly improved, and the characteristic is improved. It is possible to obtain an image display device having a stable and favorable characteristic with a small variation in the above. Furthermore, the number of treatments on the metal back layer 2 is reduced, and damage to the metal back layer 2 is minimized, so that formation of a new discharge trigger can be prevented, and a good breakdown voltage can be obtained. Characteristics can be maintained.
- the divided portion 11 of the metal back layer 2 is limited to a region corresponding to the light absorbing layer 9, and a coating layer 12 containing heat-resistant fine particles is formed in this region. Therefore, the reflection effect of the metal back layer 2 is hardly reduced, and the luminous efficiency is not reduced by the formation of the coating layer 12, so that a high-luminance display can be obtained.

Next, after the base film was peeled off and the A1 film was adhered on the phosphor screen, the A1 film was subjected to press treatment and baking treatment, respectively. Thus, a substrate A having the metal back layer transferred and formed on the phosphor screen was obtained.

In a region where no coating layer was formed, a uniform deposited film of Ba was formed. Then, a film-shaped Ba getter layer separated by a coating layer containing silica fine particles as a main component was formed. After that, necessary processing such as sealing was performed to complete the FED.

That is, as in Example 2, after forming a light absorbing layer (surface resistance value 1 ⁇ 10 14 ⁇ 10 port) using a black pigment paste on a glass substrate, a metal back layer was formed on the phosphor screen. . Then, acetic acid aqueous solution ( ⁇ 5. 5 hereinafter) and ⁇ (E chill cellulose) and solvent screen (butyl carbitol ⁇ cetearyl over G) force consisting acid paste at a position corresponding to the light-absorbing layer on the A1 film After coating by printing, baking was performed at 450 ° C for 30 minutes to form cut portions.
