Abstract

According to one embodiment, a liquid crystal display panel includes an array substrate, a counter-substrate, a liquid crystal layer and a columnar spacer. The array substrate includes a wiring including projection portion which form a dot pattern with light-blocking properties, and a first horizontal alignment film. The counter-substrate includes a second horizontal alignment film. The columnar spacer is disposed between the array substrate and the counter-substrate and is located within the dot pattern.

First claim

1 - 20 . (canceled)

21 . A liquid crystal display panel comprising:
an array substrate comprising a first wiring including a first projection portion, and a second wiring which is perpendicular to the first wiring; a counter-substrate comprising a first belt portion extending in a belt shape in parallel to the first wiring and overlapping the first wiring, and a second belt portion extending in a belt shape in parallel to the second wiring and overlapping the second wiring; and a liquid crystal layer held between the array substrate and the counter-substrate, wherein at least a part of the first projection portion is located with a displacement from the first belt portion, and is opposed to the second wiring.

22 . The liquid crystal display panel of claim 21 , wherein
the array substrate further comprises a third wiring which is perpendicular to the first wiring, the counter-substrate further comprises a third belt portion extending in a belt shape in parallel to the third wiring and overlapping the third wiring, the first wiring further includes a second projection portion, at least a part of the second projection portion is located with a displacement from the first belt portion, and is opposed to the third wiring, and both the first projection portion and the second projection portion are protruded from a first edge of the first belt portion to an outside of the first belt portion.

23 . The liquid crystal display panel of claim 21 , wherein
the first wiring further includes a second projection portion, at least a part of the second projection portion is located with a displacement from the first belt portion, and is opposed to the second wiring, the first projection portion is protruded from a first edge of the first belt portion to an outside of the first belt portion, and the second projection portion is protruded from a second edge of the first belt portion to the outside of the first belt portion.

24 . The liquid crystal display panel of claim 21 , wherein
the array substrate further comprises an insulation film which is provided between the first wiring and the second wiring.

25 . The liquid crystal display panel of claim 21 , wherein
the second wiring further includes a third projection portion, and at least a part of the third projection portion is opposed to the first wiring.

26 . The liquid crystal display panel of claim 21 , wherein
a shape of the first projection portion is semicircular, triangular, or rectangular.

27 . The liquid crystal display panel of claim 21 , wherein
the first wiring is either one of a gate line and a storage capacitance line, and the second wiring is a signal line.

an array substrate comprising a first wiring including a first projection portion, and a second wiring which is perpendicular to the first wiring; a counter-substrate comprising a first belt portion extending in a belt shape in parallel to the first wiring and overlapping the first wiring, and a second belt portion extending in a belt shape in parallel to the second wiring and overlapping the second wiring; a liquid crystal layer held between the array substrate and the counter-substrate; and a spacer disposed between the array substrate and the counter-substrate, wherein at least a part of the spacer is opposed to an intersection part between the first belt portion and the second belt portion, and at least a part of the first projection portion is located with a displacement from the first belt portion, and is opposed to the second wiring.

30 . The liquid crystal display panel of claim 29 , wherein
the array substrate further comprises a third wiring which is perpendicular to the first wiring, the counter-substrate further comprises a third belt portion extending in a belt shape in parallel to the third wiring and overlapping the third wiring, the first wiring further includes a second projection portion, at least a part of the second projection portion is located with a displacement from the first belt portion, and is opposed to the third wiring, and both the first projection portion and the second projection portion are protruded from a first edge of the first belt portion to an outside of the first belt portion.

31 . The liquid crystal display panel of claim 29 , wherein
the first wiring further includes a second projection portion, at least a part of the second projection portion is located with a displacement from the first belt portion, and is opposed to the second wiring, the first projection portion is protruded from a first edge of the first belt portion to an outside of the first belt portion, and the second projection portion is protruded from a second edge of the first belt portion to the outside of the first belt portion.

32 . The liquid crystal display panel of claim 29 , wherein
the array substrate further comprises an insulation film which is provided between the first wiring and the second wiring.

33 . The liquid crystal display panel of claim 29 , wherein
the second wiring further includes a third projection portion, and at least a part of the third projection portion is opposed to the first wiring.

34 . The liquid crystal display panel of claim 29 , wherein
a shape of the first projection portion is semicircular, triangular, or rectangular.

35 . The liquid crystal display panel of claim 29 , wherein
the first wiring is either one of a gate line and a storage capacitance line, and the second wiring is a signal line.

36 . The liquid crystal display panel of claim 29 , wherein
the first wiring is a signal line, and the second wiring is either one of a gate line and a storage capacitance line.
