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.

A liquid crystal display panel comprising:
- an array substrate comprising a wiring including projection portions which form a dot pattern with light-blocking properties, and a first horizontal alignment film;
- a counter-substrate comprising a second horizontal alignment film which is opposed to the first horizontal alignment film, the counter-substrate being arranged with a gap from the array substrate;
- a liquid crystal layer held between the array substrate and the counter-substrate;
- and
- a columnar spacer which is disposed between the array substrate and the counter-substrate and is located within the dot pattern;
- wherein
- the wiring comprises a gate line, a storage capacitance line which is disposed with a distance from the gate line and is parallel to the gate line, and a signal line which is perpendicular to the gate line and the storage capacitance line,
- the counter-substrate comprises a belt portion which extends in a belt shape in parallel to the gate line and the storage capacitance line, and has side edges overlapping the gate line and the storage capacitance line, and
- the dot pattern is formed at an intersection part between the gate line, the storage capacitance line and the belt portion, on the one hand, and the signal line, on the other hand.
