本発明はエレクトロクロミック（以下、ＥＣという。）
表示装置の製造方法に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention is an electrochromic (hereinafter referred to as EC)
The present invention relates to a method of manufacturing a display device.

より、電荷の移動が妨げられる。(Conventional technique v#) Conventional EC display devices are classified into solid type and solution type depending on the shape of the electrolyte layer, but the latter has drawbacks such as liquid leakage, so it was developed by FiIllf from the point of view of ease of handling. is desired. When producing such an EC* display device,
Generally, the EC layer and electrolyte layer are formed separately. That is, it is produced by laminating ECMIf on an electrode, then further laminating an electrolyte layer, and sandwiching the layer with a counter electrode. Therefore, the presence of a clear interface between the EC layer and the electrolyte layer prevents charge transfer.
またＥＣ層を積層した段階でＥＣ層に酸素や水分が吸着
するためＥＣ反応に悪影響を及ぼすことがある。Further, at the stage of laminating the EC layer, oxygen and moisture are adsorbed to the EC layer, which may adversely affect the EC reaction.

表示性能が悪い。In an attempt to improve these shortcomings, a method was proposed in JP-A-63-2005 in which monomers were dissolved in a polymer electrolyte in advance, and then an EC layer was formed by sandwiching the two sides between electrodes and applying a voltage.
It is shown in the publication No. 291037. According to this method, since the interface between the electrolyte layer and the EC layer is homogeneous, no interference with charge transfer or adsorption of other substances occurs. However, in this method, because the 7-mer is dissolved throughout the polymer electrolyte, electrolytic polymerization products are generated not only on the working electrode but also on the counter electrode.
Display performance is poor.
