Abstract: To reduce glare due to external light during an image display state of a variable mirror-equipped display apparatus.
The variable mirror-equipped display apparatus that is electrically switchable between a mirror state and an image display state including: a display unit that emits image light; a reflective polarizer disposed on a light emission side of the display unit; a liquid crystal lens disposed opposite the display unit with the reflective polarizer interposed therebetween; and a control device that controls operation of the display unit and the liquid crystal lens; where the liquid crystal lens is electrically switchable under the control of the control device between a first state which exhibits a lens effect and a second state which does not exhibit the lens effect.

Abstract: To provide an electro-optical apparatus suitably usable as a reflective display apparatus with excellent visibility. A first substrate having a first electrode on one surface side, a second substrate having a second electrode on one surface side and arranged opposing the first substrate, an electrolyte layer having material used for electrolytic deposition and disposed between the first electrode and the second electrode are included. Each of the first electrode and the second electrode has a concave-convex configuration on one surface side that is in contact with the electrolyte layer. Surface roughness Ra of one side of the first electrode is 0.4 μm or more, and surface roughness Ra of one surface side of the second electrode is 0.02 μm or more and relatively smaller than the surface roughness of the first electrode.

Abstract: To provide a liquid crystal element with a high contrast ratio capable of achieving both optical control that utilizes a memory property and optical control capable of supporting moving image displays. The two substrates are disposed with an angle formed by the respective orientation processing directions from 0° to less than 40°. The liquid crystal layer includes chiral material capable of generating a second orientation state that includes a twist different from that of the first orientation state in the liquid crystal molecules of the layer. The liquid crystal layer transitions from the second orientation state to the first orientation state and vice versa by the application of an electric field, and returns to the second orientation state when an electric field is applied in the second orientation state, thereby generating an orientation change in accordance with the size of the electric field, and the electric field is subsequently released.
