Abstract

A liquid crystal display panel having a plurality of pixels and a first substrate and a second substrate that are so disposed as to be opposed to each other and sandwich a liquid crystal layer, each of the pixels including a display sub-pixel and a viewing angle control sub-pixel, the liquid crystal display panel, includes: a first electrode configured to operate as a pixel electrode and be formed in the first substrate and in each of the display sub-pixels and the viewing angle control sub-pixels; and a second electrode configured to operate as a common electrode and be formed in the first substrate and over the first electrode with intermediary of an insulating film across the display sub-pixels and the viewing angle control sub-pixels, wherein an auxiliary interconnect electrically connected to the second electrode is formed in the viewing angle control sub-pixel.

Claims (20)

1. A liquid crystal display panel having a plurality of pixels and a first substrate and a second substrate that are so disposed as to be opposed to each other and sandwich a liquid crystal layer, each of the pixels including a display sub-pixel and a viewing angle control sub-pixel, the liquid crystal display panel, comprising:

a first electrode configured to operate as a pixel electrode and be formed in the first substrate and in each of the display sub-pixels and the viewing angle control sub-pixels; and

a second electrode configured to operate as a common electrode and be formed in the first substrate and over the first electrode with intermediary of an insulating film across the display sub-pixels and the viewing angle control sub-pixels, wherein

an auxiliary interconnect electrically connected to the second electrode is formed in the viewing angle control sub-pixel.

2. The liquid crystal display panel according to claim 1 , wherein

a signal line and a scan line are formed in the viewing angle control sub-pixel of the first substrate, and

the auxiliary interconnect is formed in the same layer as a layer of the signal line or the scan line.

3. The liquid crystal display panel according to claim 1 , wherein

the auxiliary interconnect is located on an end part side of the first electrode of the viewing angle control sub-pixel.

4. The liquid crystal display panel according to claim 1 , wherein

a plurality of slits are formed in the second electrode of the viewing angle control sub-pixel, and

the auxiliary interconnect has an extension part extended from the auxiliary interconnect at a position corresponding to a center of width of the slit.

5. The liquid crystal display panel according to claim 1 , wherein

a plurality of slits are formed in the second electrode of the viewing angle control sub-pixel, and

the auxiliary interconnect has an extension part extended from the auxiliary interconnect at a position corresponding to a center of a region between the slits adjacent to each other.

6. The liquid crystal display panel according to claim 1 , wherein

the auxiliary interconnect is composed of a metal material.

7. An electronic apparatus, comprising

the liquid crystal display panel having a plurality of pixels and a first substrate and a second substrate that are so disposed as to be opposed to each other and sandwich a liquid crystal layer, each of the pixels including a display sub-pixel and a viewing angle control sub-pixel, the liquid crystal display panel, including: a first electrode configured to operate as a pixel electrode and be formed in the first substrate and in each of the display sub-pixels and the viewing angle control sub-pixels; and a second electrode configured to operate as a common electrode and be formed in the first substrate and over the first electrode with intermediary of an insulating film across the display sub-pixels and the viewing angle control sub-pixels, wherein

an auxiliary interconnect electrically connected to the second electrode is formed in the viewing angle control sub-pixel.
