Abstract: This invention is an exposure apparatus for exposing a photoalignment film provided on a substrate. The exposure apparatus includes a light source and a photomask, and exposes the photoalignment film through the photomask while scanning the light source or the substrate. When a direction in which the light source or the substrate is scanned is taken as a scanning direction, and a direction that is orthogonal to the scanning direction is taken as a vertical direction, the photomask includes a first region and a second region that is adjacent to the first region in the vertical direction. The first region includes a plurality of first transparent portions inside a first light-shielding portion. The plurality of first transparent portions are arranged in the vertical direction. The second region includes a plurality of second transparent portions inside a second light-shielding portion.

Abstract: A display element having high response property, wide viewing angle property, and high contrast property, and exhibiting a wide driving temperature range and excellent durability and reliability. Between two facing substrates (1, 2), a cholesteric liquid crystal layer (3) made of a liquid crystal material exhibiting a cholesteric phase whose spontaneous twist pitch is shorter than a wavelength of visible light is provided. Facing planes of the substrates (1, 2) are provided with alignment films (8, 9) for aligning liquid crystal molecules near the interface of the substrate in a specific direction. Furthermore, the planes are provided with electrodes (4, 5) for applying an electric field on the cholesteric liquid crystal layer (3) in a direction substantially parallel to a plane of each substrate. The cholesteric liquid crystal layer (3) exhibits optical isotropy in the direction parallel to the plane of each substrate when no voltage is applied.
