Title: Color filter
Inventor: WATANABE KANE
IPC: G02F1/1335
Filed: 1989-02-02
Abstract: PURPOSE:To obviate the flocculation of coloring materials and to prevent the degradation in the light transmittance of a peak wavelength by incorporating barium sulfate having <=0.2mum average grain size into the coloring layer of the filter. CONSTITUTION:The barium sulfate having <=0.2mum average grain size is incorporated into the colored layer of the color filter formed by dispersing the coloring materials in a transparent resin and is well dispersed by a dispersing machine. The barium sulfate particles, therefore, exist between the finely ground particles of the coloring materials to weaken the flocculating force of the fine coloring materials. The dispersion in the fine particles of the coloring material is possible in this way and the degradation in the light transmittance particularly at the peak wavelength is prevented without impairing the optical characteristics. The scattering of light by the barium sulfate is conspicuous and a contrary effect is resulted if the average grain size of the barium sulfate is >=0.2mum.

In order to prevent the temperature detected by the sensor 12 from dropping below a preset specific test temperature, the temperature controller 10 controls current transmitted through the coil 11. When the temperature of the end portion of each catch portion 3 being detected by the sensor 9 drops below a predetermined temperature corresponding to the size of the test piece, a cooling device 7 is repeatedly stopped and driven for a fixed time so that the temperature distribution of the test piece 1 is stabilized. Therefore, the rupture position of the test piece due to a tension test can be concentrated at the center portion of the test piece.
