Two-screen display device

摘要

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.

主权项

1. 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, the aspect ratio of each sub-pixel corresponding to a ratio of a repetition unit of sub-pixels in a row direction to a repetition unit of sub-pixels in a column direction; 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 a first row in which said openings of said parallax barrier are disposed in a region between said first sub-pixel and said second sub-pixel, which receive the image signal from the identical source line, and a second row in which said openings of said parallax barrier are disposed in a region between said first sub-pixel and said second sub-pixel, which receive the image signal from the different source lines, are alternately disposed in said display region; and the openings of said parallax barrier in the first row are each shifted in an extending direction of said gate lines from the openings of said parallax barrier in the second row.
