A liquid crystal device is constituted by a first substrate and a second substrate disposed opposite to each other, and a liquid crystal lacking cholesteric phase disposed between the first and second substrates. The first substrate has a surface contacting the liquid crystal showing a surface energy .gamma..sub.1 (dyne/cm) and the second substrate has a surface contacting the liquid crystal showing a surface energy .gamma..sub.2 (dyne/cm) satisfying .gamma..sub.1 >.gamma..sub.2. The surface of the first substrate is provided with a film of a polyimide or an aromatic polyamide, and the surface of the first substrate having been selectively subjected to a uniaxial aligning treatment. As a result, the liquid crystal can assume a stable alignment state of a bookshelf structure or one close thereto having a small layer inclination angle. The resultant device can show a high contrast and a good responsiveness.
A liquid crystal device, comprising:
A process for producing a liquid crystal device of the type comprising a first substrate and a second substrate disposed opposite to each other, and a liquid crystal lacking cholesteric phase disposed between the first and second substrates;
