Abstract: A rechargeable battery includes an electrode assembly including a first electrode plate, a second electrode plate, and a separator, a case accommodating the electrode assembly and having both ends open, a first cap plate coupled to one end of the case, a second cap plate coupled to the other end of the case, a first cover member disposed to cover the first cap plate and including a first electrode terminal exposed upwardly, and a second cover member disposed to cover the second cap plate and including a second electrode terminal exposed upwardly. A first electrode lead of the electrode assembly passes through the first cap plate to be electrically connected to the first electrode terminal of the first cover member, and a second electrode lead of the electrode assembly passes through the second cap plate to be electrically connected to the second electrode terminal of the second cover member.

Abstract: An optical path control member according to one embodiment comprises: a first substrate; a first electrode arranged on the first substrate; a second substrate arranged on the first substrate; a second electrode arranged below the second substrate; and a light conversion unit arranged between the first electrode and the second electrode, wherein the light conversion unit includes a barrier part and an accommodation part, which are alternately arranged, the accommodation part has a light transmittance that changes according to applied voltage, the first electrode extends in a first direction and includes a plurality of pattern electrodes spaced from each other, and the barrier part and the accommodation part extend in a second direction that differs from the first direction.

Abstract: An optical path control member according to an embodiment comprises: a lower substrate; a lower electrode disposed on the upper surface of the lower substrate; an upper substrate disposed on the lower substrate; an upper electrode disposed on the lower surface of the upper substrate; a light conversion unit disposed between the lower electrode and the upper electrode; and an adhesive layer provided between the light conversion unit and the upper electrode, wherein the light conversion unit includes partition wall parts and accommodation parts that are alternately disposed, the accommodation part has a light transmission rate that varies according to the application of voltage, and, when the ratio of the thickness of the accommodation part to the dielectric constant thereof (thickness/dielectric constant) is defined as A and the ratio of the thickness of the adhesive layer to the dielectric constant thereof (thickness/dielectric constant) is defined as B, the value of A is greater than the value of B.
