Display bright in contrast can be obtained without discrination and flicker in the display device of the direct vision type whose pixel pitches are short to 20 μm or less. A liquid crystal panel is driven through the frame inverse driving method, and the vertical frame frequency is set to 120 Hz or more. Also, each of the pixels is arranged to correspond to one of R, G and B of color filters disposed on a TFT substrate side.

1. Field of the Invention
The present invention relates to a driving method suitable for a display device using a display medium such as liquid crystal in which pixels are arranged in a matrix. Also, the present invention relates to a display device which conducts display by using the driving method. In particular, the present invention relates to an active matrix liquid crystal panel (liquid crystal panel) of the direct vision type.
2. Description of the Related Art
These and other objects, features and advantages of this invention will become more fully apparent from the following detailed description taken with the accompanying drawings in which:
FIG. 1 is a timing chart of a liquid crystal panel in accordance with the present invention;
FIG. 2 is a schematic diagram showing a TFT substrate in accordance with the present invention;
Now, a description will be given in more detail of preferred embodiments of the present invention with reference to the accompanying drawings.
The structure of the present invention will be described as compared with the conventional structure. An example using a non-interlace scanning will be described in the present specification. However, the present invention is not limited to the non-interlace scanning, but may be applied to other scanning systems such as an interlace scanning.
FIG. 2 is a diagram showing the structure of an active matrix liquid crystal panel in accordance with the present invention. A source signal line driving circuit 1801 and a gate signal line driving circuit 1802 are generally called “driving circuit”. In recent years, the driving circuit may be formed on the same substrate integrally with a pixel portion 808 in which pixels are disposed in a matrix.
