Abstract

PURPOSE:To make best use of the good look of electrochromics by fixing an element and supporting base body by a color adhesive agent. CONSTITUTION:The color adhesive agent 17 is injected and cured along the inside peripheral surface on an upper counter electrode side and interconnector 15 of an electrochromic element 1 to secure the element 1, the connector 15 and the supporting base body 14. Compressive stress is exerted between the base body 15 and the element 1 by the shrinkage when the adhesive agent cures; therefore, the need for a press plate 16 is eliminated or said plate is simplified (reduced in thickness) and is merely stuck to the body 2. The appearance is thereby made excellent and since the base body 2 is relieved of the pressure from the plate 16, an accident such as damage is hardly generated.

Conventionally, when producing a display panel using such an electrochromic element, as shown in FIG. The assembled electrochromic elements 1 were placed on an interconnector 15 placed on a support base 14 provided with extraction electrodes 13 to form a panel. For this reason, the adhesive 11 is attached to each electrode and connector 1 constituting the element.
Since the adhesive protrudes over the lead electrodes 3 and 5' for connection with the adhesive 5, which often causes poor contact, it is necessary to precisely apply the adhesive by controlling the application position and application amount.

In addition, in order to maintain good contact between the base 2 and the interconnector 15, a certain amount of force must be applied to the base 2 and the lead-out electrode 13.
It is necessary to use a presser plate 16 with a certain degree of rigidity, and the supporting base 1
4 and the holding plate 16 so that a compressive force is applied thereto.

Means for Solving Problem C] The display panel of the present invention, which was discovered as a means for solving the above problems, uses an electrochromic film comprising a transparent display electrode, an electrochromic i, a layer, and a counter electrode as constituent components. The present invention is a display panel comprising an element and a supporting base for supporting the element, characterized by a layer in which the element and the supporting base are fixed to each other with a color adhesive.

The display panel shown in FIG. 1 has color adhesive applied along the upper counter electrode side of the electrochromic element 1 and the inner peripheral surface of the interconnector 15. 17 is injection hardened to secure the element 1, the connector 15 and the support substrate 14. Compressive stress is applied between the support base 15 and the electrochrome element 1 due to shrinkage when the adhesive hardens, so it is possible to omit the presser plate 16 or simplify it (make it thinner) and attach it to the base 2. It can be simply pasted on.
