摘要： PROBLEM TO BE SOLVED: To reduce the unevenness of transmitted light quantity in a liquid crystal light control element and the differences of characteristics among individual products.
SOLUTION: A liquid crystal layer 163 is interposed between transparent substrates 161, 162 of the liquid crystal light control element 16, and a voltage is applied to the liquid crystal layer 163 with transparent electrodes 164, 165 disposed on mutually opposing faces of the transparent substrates 161, 162. And with respect to wire shapes of the transparent electrodes 164, 165, when a wire width in a wire portion of the electrode is represented by W, a wire length therein by L, wire thickness therein by d, and wire resistance therein by r, the shape of the electrode is formed in a range where an inequality 3×10
-3 ≤(L/W)≤2×10
5 is satisfied, so as to make an equation R=rL/(Wd) to calculate a resistance value R hold.

摘要： PROBLEM TO BE SOLVED: To provide an electric dimmer element with which a shading phenomenon of an optical system is effectively eliminated while reducing the size of the electric dimmer element and lowering the cost thereof, a lens barrel and an imaging apparatus.
SOLUTION: The liquid crystal dimmer element 16 has a liquid crystal layer 1614 sealed in between two electrodes, i.e. between first and second transparent electrodes 1606, 1608 placed opposite to each other, wherein transmittance of light passing through the layer in the direction of the first and second transparent electrodes 1606, 1608 is varied corresponding to a driving signal applied to the first and second transparent electrodes 1606, 1608. The thickness of the liquid crystal layer 1614 is formed with a dimension gradually decreasing as going from a center part of the contour to the periphery. In other words, the thickness of the liquid crystal layer 1614, which is the dimension of a gap between the first and second transparent electrodes 1606, 1608, is constructed so as to be partly different from one another along the first and second transparent electrodes 1606, 1608.
