Abstract
Abstract A liquid crystal panel comprising base plates, at least one of which is a plastic base plate provided with a transparent electrode, and a liquid crystal interposed between the substrates, is provided by forming an orientation controlling film of a composition comprising an organic indium compound and an organic zirconium compound or of a composition comprising an organic indium compound, a polyester resin and an isocyanate resin on the plastic substrate, or is produced by arranging at least two monoaxially stretched films as the substrates so that their stretched directions are in parallel or in counter-directionally parallel with each other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
49 words
A liquid crystal panel comprising plastic films as substrates, which comprises as the plastic films at least two monoaxially stretched films disposed to have their stretched directions substantially in parallel or in counter-directionally parallel with each other and a liquid crystal filling the gap between the monoaxially stretched films.
Claim 2
Dependent Claim
49 words
A liquid crystal panel comprising plastic films as substrates, which comprises as the plastic films at least two monoaxially stretched films disposed to have their stretched directions substantially in parallel or in counter-directionally parallel with each other and a liquid crystal filling the gap between the monoaxially stretched films.
Claim 3
Dependent Claim
41 words
The liquid crystal panel according to claim 1, the stretched direction of a monoaxially stretched plastic film forming one substrate forms an angle of 10° or less with the stretched direction of another monoaxially stretched polyester film forming the other substrate.
Claim 4
Dependent Claim
41 words
The liquid crystal panel according to claim 1, the stretched direction of a monoaxially stretched plastic film forming one substrate forms an angle of 5° or less with the stretched direction of another monoaxially stretched polyester film forming the other substrate.
Claim 5
Dependent Claim
32 words
The liquid crystal panel according to claim 1, wherein the stretched directions of said at least two monoaxially stretched films are in a direction oblique to the machine direction of the films.
Claim 6
Dependent Claim
28 words
The liquid crystal panel according to claim 1, wherein the stretched directions of said at least two monoaxially stretched films are along the machine direction of the films.
Claim 7
Dependent Claim
28 words
The liquid crystal panel according to claim 1, wherein the stretched directions of said at least two monoaxially stretched films are along the transverse direction of the films.
Claim 8
Dependent Claim
19 words
The liquid crystal panel according to claim 1, wherein said monoaxially stretched films comprise a monoaxially stretched polyester film.
