失が大きかった。[Prior Art] Conventionally, in a method for manufacturing a mosaic structure consisting of phosphor dots using this type of printing method, when exposed through a shadow mask and developed, the image shown in Fig. 1 is shown. As shown, the burnt phosphor dots l-(+) grow beyond the black matrix (2) and form other phosphor dots (3).
) is formed as a protruding portion (4), which often causes color mixture with the phosphor dots (3) of other colors formed subsequently. This protruding part (4)
was difficult to discover during the manufacturing process of phosphor screens, and was not discovered until after the cathode ray tube was completed. The loss was large because it was discovered as a color defect.

。[Embodiment of the invention Co-1-Distribution 1R4 We investigated the cause of the protruding part formed on the light surface and found that the main cause was the diameter of the light source when the mosaic structure could be burned out. . Also, when the light is 1/-, the penumbra of the light source projected onto the phosphor screen through the opening 11 of the shadow mask extends to the range of the adjacent phosphor dots other than the predetermined position, and 5゛11 The relationship between the exposure sensitivity of the photon slurry film and the exposure sensitivity is c゛1?1? It has become clear that a portion of the light body will be exposed. However, in order to prevent this protrusion, the smaller the light source diameter, the lower the light intensity during exposure, so the predetermined exposure h1
The drawback is that the exposure time required to obtain the desired results becomes longer.
そこで、はみ出し部分が発生しないための光源の最大径
が最適な′ＬＸｉ径となる。Therefore, the maximum diameter of the light source that prevents any protruding portion from occurring is the optimum 'LXi diameter.

次式で表わされる。FIG. 2 is a schematic diagram of a cathode ray tube during exposure for calculating the optimum light source diameter. In the figure, from the light source (lO) with the light source diameter a to the opening (12) of the shadow mask (11)
The diameter X of the penumbra image (14) of the light source projected onto the phosphor screen (13) via (diameter D) is the distance between the shadow mask (11) and the light a;j (10) +? tlL and the distance between the shadow mask (11) and the 11 light surface (13) is expressed by the following equation.

It is necessary to make χ smaller than the sum of xO and (D−d), where d is the diameter of . Therefore, the following formula is the condition.

becomes. When the mosaic structure of the light surface is not dots but stripes, the light source diameter of the light emitting part of the light source (10) is a, and the horizontal direction +lj of the opening 11 (12) of the side mask (11) is D, the light source diameter a for the optimum light $;1(10) can be expressed by the same equation above.

When a high-pressure mercury lamp with a long axis a of mm was used, a large number of phosphors protruded around the screen, significantly deteriorating the properties, but this problem could be solved according to Example 1-1.
