Liquid crystal display panel and process for producing the same

A liquid crystal display panel comprising a pair of substrates and a liquid crystalline substance sandwiched between said substrates, in which said substrates respectively at their inner walls are provided with an alignment film, at least one of said alignment films comprising a layer of a member selected from the group consisting of the following polyimide film materials:

• 1.) a polyimide which does not have in its molecule an ether bond but has at least one moiety selected from the group consisting of a peroxide, a ketone, an ester, an amine, an amide and derivatives of said moieties;
• and
• 2.) a polyimide which has in its molecule a carbon-carbon double bond or a carbon-carbon triple bond;
• said alignment film comprising an assembly of two adjacent minute domains, said two minute domains being different from each other in pretilt angle which is defined as an angle at which liquid crystalline molecules rise from the surface of the substrate.
