Abstract

A liquid crystal display panel includes: a first substrate and a second substrate disposed so as to face each other with a liquid crystal layer being held between the first substrate and the second substrate, a first electrode and a second electrode across which an electric field is applied to the liquid crystal layer being formed on the first substrate, a subpixel for display and a subpixel for control of a view angle being disposed on the same electrode, in which a plurality of slit-like openings are formed in the second electrode in the subpixel for control of a view angle, and a light blocking member is formed in a central position of a width of each of the plurality of slit-like openings in terms of planar view.

Claims (23)

1. A transmissive liquid crystal display panel, comprising:

a first substrate and a second substrate disposed so as to face each other with a liquid crystal layer being held between said first substrate and said second substrate;

a first electrode and a second electrode across which an electric field is applied to said liquid crystal layer being formed on the first substrate;

a subpixel for display; and

a subpixel for control of a view angle being disposed on a same pixel,

wherein a plurality of slit-like openings are formed in said second electrode made of a transparent conductive material in a view angle control region of said subpixel for control of a view angle,

wherein a light blocking member is disposed on a different layer than that of the second electrode,

wherein in a planar view the light blocking member is arranged in an area to occupy a part of each of the slit-like openings and is formed in a central position of a width of each of the slit-like openings.

2. The liquid crystal display panel according to claim 1 , wherein said light blocking member is formed in a central position as well of a width of said second electrode in terms of planar view.

3. The liquid crystal display panel according to claim 1 , wherein said first electrode is formed on a lower side of said first substrate through an insulating layer, and said second electrode is formed on an upper side of said first substrate.

4. The liquid crystal display panel according to claim 1 , wherein a thin film transistor for driving either said first electrode or said second electrode is formed on said first substrate, and said light blocking member is formed in the same layer as that of either a source electrode or a gate electrode of said thin film transistor.

5. The liquid crystal display panel according to claim 1 , wherein a light blocking layer is formed on said second substrate, and said light blocking member is formed in the same layer as that of said light blocking layer.

6. The liquid crystal display panel according to claim 1 , wherein a length of said light blocking member in a position where corresponding one of said slit-like openings of said second electrode is longer than that of said light blocking member formed on a surface between corresponding ones of said slit-like openings of said second electrode.

7. An electronic apparatus comprising:

a transmissive liquid crystal display panel including

a first substrate and a second substrate disposed so as to face each other with a liquid crystal layer being held between said first substrate and said second substrate,

a first electrode and a second electrode across which an electric field is applied to said liquid crystal layer being formed on the first substrate, a subpixel for display and a subpixel for control of a view angle being disposed on a same pixel,

wherein a plurality of slit-like openings are formed in said second electrode made of a transparent conductive material in a view angle control region of said subpixel for control of a view angle,

wherein a light blocking member is disposed on a different layer than that of the second electrode,

wherein in a planar view the light blocking member is arranged in an area to occupy a part of each of the slit-like openings and is formed in a central position of a width of each of the slit-like openings.

8. The liquid crystal display panel according to claim 1 ,

wherein the light blocking member has a length that is substantially the same as a length of a long side of each of the slit-like openings, and

wherein the light blocking member has a width that is shorter than a length of a short side of each of the slit-like openings.
