Smart window having variable transmittance windowpanes

A window comprising:

• a window frame having an opening defined through which an outdoor space and an indoor space communicate;
• a pair of sashes slidably disposed in the window frame along an opening direction and a closing direction opposite to the opening direction;
• variable transmittance windowpanes configured to be fitted in the pair of sashes to open and close the opening together with the pair of sashes, the variable transmittance windowpanes having a transmittance variable by electrical connection;
• first conductive members disposed on the pair of sashes and electrically connected with the variable transmittance windowpanes to supply electric power to the variable transmittance windowpanes;
• and
• a second conductive member electrically connected with the first conductive members to supply the electric power to the first conductive members from outside the window frame,
• wherein each of the variable transmittance windowpanes includes:
• a first glass layer;
• a variable transmittance film disposed on one surface of the first glass layer, the variable transmittance film having a transmittance variable by electrical connection;
• and
• an electrode terminal protruding outside the first glass layer from the variable transmittance film, the electrode terminal being configured to make direct or indirect electrical connection between the variable transmittance film and the corresponding first conductive member,
• wherein the window further comprises a connecting terminal coupled to the corresponding sash and configured to electrically connect the electrode terminal and the first conductive member,
• wherein the electrode terminal includes a first electrode terminal member and a second electrode terminal member,
• wherein the first electrode terminal member is electrically connected with the variable transmittance film and extends toward a third surface that is a surface facing the first glass layer among faces of the sash, and
• wherein the second electrode terminal member is electrically connected with the connecting member and is configured to be bent toward a fourth surface from an end of the first electrode terminal member, the fourth surface being a surface of the first glass layer facing the third surface.

• wherein the variable transmittance windowpane further includes a second glass layer coupled to an opposite surface of the variable transmittance film, and
• wherein the first glass layer and the second glass layer are disposed such that a first separation distance by which the first glass layer is spaced apart from the corresponding sash along a direction in which the electrode terminal protrudes is smaller than a second separation distance by which the second glass layer is spaced apart from the sash along the direction in which the electrode terminal protrudes.
