後、感光体２全体を帯電させ、元の状態に戻す。When the display panel 10 is manufactured, first, the entire surface of the photoconductor 2 of the digital printer 1 is uniformly charged (charged).
The non-printed portion of the photoreceptor 2 is irradiated with laser light 3 from the laser head 4 to remove charges (exposure). And
When the toner is supplied from the toner head 5 to the photoconductor 2, the toner adheres only to a portion of the photoconductor 2 charged with the laser beam 3. The toner on the photoconductor 2 is transferred to a cylindrical blanket 7 (development). Repeat the above to get 1
When the toner of a total of four layers of the light-transmitting printing layer 8 and the three light-shielding printing layers 9 is transferred to the blanket 7, the toner on the blanket 7 is heated by a heating device (not shown) incorporated in the blanket 7. Then, it is transferred to the translucent display substrate 6 (transfer). The toner, which has been made into a gel by heating, is transferred to the translucent display substrate 6 and then dries quickly, resulting in a precise printed matter with little change in shape. After that, the entire photoconductor 2 is charged to return to the original state.

わせることができる。Further, after transferring a total of four toner layers, one translucent printing layer 8 and three light-shielding printing layers 9, to the blanket 7, the toner is transferred to the translucent display substrate 6. The above four layers can be formed simultaneously by passing the light-transmitting display substrate 6 only once. Therefore, the accuracy of the above-mentioned four layers can be improved, and printing can be performed in a short time.

Then, a pinhole 16 is formed in the light-shielding printing layer 9. In addition, since the photoconductor 2 always returns to the predetermined initial position and performs processing from the initial position, the pinhole 16 is generated at the same position regardless of how many times the light-shielding print layer 9 is printed.

By repeatedly forming the front and back inverted light-shielding printing layer 11 by a plurality of layers, it is possible to easily create the data of the back light-shielding printing layer 11 simply by inverting the data of the light-shielding printing layer 9 on the front side. it can. Then, the translucent display substrate 6
Is turned over, and the front and back inverted light-shielding printing layer 11 is formed on the back side of the light-transmitting display substrate 6 by using the digital printing machine 1 so that the light-shielding printing layer 9 and the front-back inverted light-shielding printing layer 11 Since the position of the pinhole 16 is shifted, light leakage can be prevented even if the pinhole 16 is formed. In addition, since the front and back inverted light-shielding printing layer 11 formed on the translucent display substrate 6 turned over has the same shape as the light-shielding printing layer 9 when viewed from the surface, only the position of the pinhole 16 can be shifted. .
