A molded resin product includes a plurality of protrusions formed in a predetermined region. A histogram indicating a height distribution of the plurality of protrusions has two peaks having a boundary height as a boundary therebetween. In a case where protrusions having height equal to or smaller than the height Hx are first protrusions and protrusions having height larger than the boundary height are second protrusions among the plurality of protrusions, an arithmetic mean curvature of the first protrusions is smaller than an arithmetic mean curvature of the second protrusions.

A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal assuming two stable states disposed between the opposing electrodes. The opposing inner surfaces of the pair of substrates have been subjected to an aligning treatment such that the liquid crystal placed in one of the two stable states moves under application of an electric field in a direction identical to one in which the liquid crystal placed in the other of the two stable states moves under the application of the electric field. The liquid crystal device has an effective optical modulation region and a peripheral region outside the effective optical modulation region, wherein the effective optical modulation region and the photosensitive member have been subjected to different aligning treatments. In the liquid crystal device thus constituted, a liquid crystal movement liable to cause yellowing or fluctuation in drive parameters otherwise is effectively compensated by a liquid crystal movement in the peripheral region.

Liquid crystal device and process for production thereof

A ferroelectric liquid crystal device of a cell structure having a suppressed increase of cell thickness along a cell side is constituted by disposing a ferroelectric liquid crystal between a pair of electrode plates each sequentially provided with an electrode, an insulating film and an alignment film on a substrate. The alignment film is provided with a surface unevenness for suppressing a liquid crystal movement causing the increase in cell thickness. The surface unevenness is provided to the alignment film directly or to the insulating film below the alignment film, e.g., by wet forming the relevant film by using at least two solvents having different boiling points or dispersing fine particles within the relevant film, optionally followed by removal of the fine particles.

A liquid crystal device is produced through the steps of: a) disposing a pair of substrates opposite to each other so as to form a cell between the substrates while leaving a first aperture and a second aperture for communication with an exterior and forming an effective optical modulation region between the first and second apertures, b) heating a liquid crystal material for filling the cell, and c) filling the cell with the liquid crystal material by injecting the liquid crystal material through the first aperture under a pressure difference held between the first and second apertures and, after a prescribed period, allowing the liquid crystal material to be discharged out of the second aperture. In the step c), the first aperture, the second aperture and the effective optical modulation region of the cell may preferably receive external pressures P1, P2 and P3, respectively, satisfying P1&gt;P2 and -1 kg.f/cm.sup.2 .ltoreq.P1-P3.ltoreq.0.5 kg.f/cm.sup.2.
