Abstract

An object of the invention is to provide an inexpensive method of manufacturing a liquid crystal display apparatus having a low resolution by utilizing a TFT substrate adapted for a high-definition liquid crystal display apparatus. The liquid crystal display apparatus having a low resolution is realized in an inexpensive way by using the TFT substrate adapted for a high-definition liquid crystal display apparatus and by combining a new color filter substrate and driver ICs suited to a new driving method, the new color filter substrate being formed such that one pixel group is formed by pixels of a color filter substrate wherein the number of pixels is the product of three by an integer.

Claims

1. A liquid crystal display apparatus comprising:

a pair of substrates;

a plurality of pixel electrodes which are arranged in a matrix form, formed on one substrate of the pair of substrates; and

a plurality of color filters of n (n is an integer of two or more) number of colors corresponding to the plurality of pixel electrodes, the plurality of color filters being arranged so that color filters for a same color sequentially form m (m is an integer of two or more) number of columns,

wherein n×

m×

1 (1 is a natural number) pixels form one pixel group.

2. The liquid crystal display apparatus of

claim 1

, wherein each of the plurality of pixel electrodes is provided with a thin film transistor.

3. The liquid crystal display apparatus of

claim 1

, wherein the n number of colors are three primary colors consisting of red, green and blue.

4. The liquid crystal display apparatus of

claim 1

, wherein the color filters are formed on the other substrate of the pair of substrates.

5. The liquid crystal display apparatus of

claim 1

, comprising:

a driver the same as that used in a liquid crystal display apparatus having color filters of n number of colors arranged sequentially, and different color filters and controller from those used in the latter liquid crystal display apparatus.

6. The liquid crystal display apparatus of

claim 1

, the liquid crystal display apparatus in which the n×

m×

1 pixels form one pixel group being constructed by short-circuiting a bus line extending in the direction of column at every m pixels or a bus line extending in the direction of row at every one pixel.

7. A method of manufacturing a liquid crystal display apparatus comprising:

a step of laminating a thin film transistor substrate on which a plurality of pixel electrodes are arranged in a matrix form, and a color filter substrate on which a plurality of color filters of n (n is an integer of two or more) number of colors corresponding to the plurality of pixel electrodes, the plurality of color filters being arranged so that color filters of a same color sequentially form m (m is an integer of two or more) number of columns, to form one pixel group consisting of n×

m×

1 (1 is a natural number) pixels.
