Abstract

A two-screen display device, in which an increase of production cost can be suppressed while the same resolution as an image of a usual (one-screen display) device is maintained, is provided. In a liquid crystal display panel of the two-screen display device, each of a first sub-pixel for first image and a second sub-pixel for second image has an aspect ratio of about 6:1. A source line supplies an image signal to both the first sub-pixel and the second sub-pixel. Each row of the sub-pixel includes a gate line (first gate line) that drives the first sub-pixel and a gate line (second gate line) that drives the second sub-pixel. An opening of a parallax barrier is disposed in a region between the first sub-pixel and the second sub-pixel.

Claims21

Dependent claims

A two-screen display device comprising:

a first sub-pixel that is of a sub-pixel for a first image and a second sub-pixel that is of a sub-pixel for a second image, the first sub-pixel and the second sub-pixel being adjacent to each other, each of the first sub-pixel and the second sub-pixel having an aspect ratio of about 6:1;
a source line that supplies an image signal to both said first sub-pixel and said second sub-pixel;
a first switching element that is connected between said source line and said first sub-pixel;
a second switching element that is connected between said source line and said second sub-pixel;
a first gate line that is of a gate line supplying a driving signal to a control electrode of said first switching element to drive said first sub-pixel;
a second gate line that is of a gate line supplying a driving signal to a control electrode of said second switching element to drive said second sub-pixel;
a display region in which a plurality of sets of said first sub-pixel and said second sub-pixel are arrayed into a two-dimensional matrix shape;
and
a parallax barrier that is of a light shielding film provided on said display region, said parallax barrier including a plurality of openings arrayed in a region between said first sub-pixel and said second sub-pixel, which are adjacent to each other.
