现有技术中，为了避免电致变色器件的上下汇流短路，通常仅在电致变色器件的单侧设置一个汇流条，在单侧设置一个汇流条结构的目的是为了避免两个汇流条接触产生短路情况，但是对于面积较大的电致变色器件，通过单侧布置一个汇流条的结构会大大减少对电致变色器件的面阻(面阻是指在单位正方形面积条件下的电阻阻抗，一般是1cm边长的正方形面积)降低效果，导致电致变色器件的变色速度减慢，变色出现迟钝等现象，极大影响电致变色器件的可靠性。

其中，为了提高封胶层12的保护质量，在封胶层12与第一导电段10具有间隙，用于避免第一 导电段10与外部电源连接的过程中影响封胶层12的密封质量，提高封胶层12对电致变色层2保护的稳定性。
