An objective of the present invention is to provide a variable sheet wherein a light transmittance is changed by an electrical drive. One implementation of the present invention provides a light transmittance variable sheet comprising: an upper part electrode; a lower part electrode located spaced apart and opposite to the upper part electrode; and a space located between the upper part electrode and the lower part electrode, wherein the space comprises a plurality of structures that accommodate inks comprising electrophoretic particles, each structure is located with a bottom surface adjacent to each other, and an area of a cross-section of the structure is much more smaller on that of an area of a cross-section of a lower part electrode side than that of an area of a cross-section of an upper part electrode side. Therefore, the present invention is capable of adjusting light transmittance.
본 발명의 목적은, 전기적 구동에 의해 광 투과율이 변화하는 가변 시트를 제공하는 것이다. 본 발명의 한 구현예는, 상부 전극; 상기 상부 전극에 대향하여 이격하여 위치하는 하부 전극; 및 상기 상부 전극 및 상기 하부 전극 사이에 위치하는 공간을 포함하고, 상기 공간은 전기 영동 입자가 포함된 잉크를 수용하는 복수개의 구조체를 포함하며, 각각의 구조체는 밑면이 서로 인접하여 위치하고, 상기 구조체의 단면의 면적은 상부 전극 측의 단면의 면적보다 하부 전극 측의 단면의 면적이 더 작은, 광 투과율 가변 시트를 제공한다.
