ある。またこのような測定器は測定までの準備がたんへ
んであり、測定器も簡単に誰でも扱えるものではないた
め、多量数の測定物がある場合などには入手と時間がた
いへんにかかつた。The conventional color filter combined with the color image display cell has a structure in which only the color elements of the portion (a) of FIG. 1, that is, the portion used for image or character display are formed. Therefore, when performing a quality evaluation test such as light resistance and heat resistance of a color image display, it is necessary to measure the color difference value change of each element of (1), (2) and (3). In this case the color element (1)
If the outer dimensions of (2) and (3) are smaller than 200 μm square, there is a disadvantage that it is impossible to accurately measure changes in color difference values unless a very expensive measuring device is used. In addition, such a measuring instrument is not ready for measurement, and it is not easy for anyone to handle.Therefore, if there are a large number of items to be measured, it would be very difficult to obtain and time. .

のサンプルによる評価が可能となつた。In order to achieve the above object, the present invention comprises a liquid crystal panel and a color filter, the color filter,
Red, green, and blue color elements are arranged on a transparent base material, and the color elements are provided on a portion of the transparent base material corresponding to an image display area of the liquid crystal panel. In the color liquid crystal display device arranged, the color elements are
It is characterized in that it is also arranged in a portion of the transparent substrate that does not correspond to the image display area. Measurements can be made with a much cheaper measuring instrument than the above-mentioned measuring instrument, the number of man-hours required for quality evaluation is greatly reduced, and it is possible to perform evaluation with a much larger number of samples than before.

The same symbol is the same element. (1), (2), and (3) are color elements, which have a configuration of red, green, and blue.
(4), (5), and (6) are color elements for measurement, which are larger than the color elements for display and are 300 to 400 μm square. This color element is for evaluating the color difference values of the three colors, but if the dimensions are different from the color elements for image display and the dimensions are different, each color will be different when forming and coloring the color element. Therefore, designs with extremely different dimensions should be avoided.

ンとなつた。As described above, according to the present invention, a liquid crystal panel and a color filter are provided, and the color filter has three color elements of red, green and blue arranged on a transparent substrate. Further, in the color liquid crystal display device in which the color element is arranged in a portion corresponding to the image display area of the liquid crystal panel on the transparent substrate, the color element is the image display area on the transparent substrate. Since it is also arranged in the part that does not correspond to, the color meter with a precision microscope (for example, MMSP of Olympus Corporation) is used to measure the color of the color filter, and the device is large and easy to operate. Although it was time consuming, it became possible to use a portable colorimeter (eg Topcon BM-5). As a result, the time spent for color measurement in quality tests such as light resistance and heat resistance of color filters can be greatly reduced, resulting in cost reduction.
