Description
Technical field
The present invention relates to Reflexible color LCD and manufacture method thereof, particularly by the stacked colour that constitutes of reflection liquid crystal display (reflective LCD) is shown cholesteric liquid crystal display and manufacture method thereof.
Background technology
Colored show that cholesteric liquid crystal display is that the reflection liquid crystal display (reflective LCD) that reflects by the wavelength that will select to stipulate is stacked and constitutes.For example, as shown in Figure 9, colored demonstration cholesteric liquid crystal display 100 possesses: the light absorbing zone 101 of black; Be layered in the red reflex LCD105 on the light absorbing zone 101, it is formed with the red reflex liquid crystal layer 102 that shows red reflected colour between substrate 103,104; Be layered in the green reflective LCD 109 on the red reflex LCD105, it is formed with the green reflective liquid crystal layer 106 that shows green reflected colour between substrate 107,108; With the blue reflective LCD 113 that is layered on the green reflective LCD 109, it is formed with the blue reflective liquid crystal layer 110 that shows blue reflected colour between substrate 111,112.Like this, the reflective LCD 105,109,113 of the reflected colour by will showing RGB (red, green, blue) 3 looks is layered on the light absorbing zone 101, thereby makes and coloredly show that cholesteric liquid crystal display 100 can carry out full color and show.
As the substrate 103,104,107,108,111,112 of above-mentioned reflective LCD 105,109,113, use glass substrate that constitutes by glass or the flexible base, board (for example opening the 2004-2765 communique) that constitutes by resins such as polycarbonate with reference to the spy with light transmission.
But, using under the situation of glass substrate as the substrate 103,104,107,108,111,112 of reflective LCD 105,109,113, as shown in Figure 9, because the thickness of slab t of glass substrate is thicker, so (reflective liquid crystal interfloor distance A) is elongated for the distance that red reflex liquid crystal layer 102 and blue reflective liquid crystal layer are 110, produce parallax (angle dependence of visuognosis) B based on this reflective liquid crystal interfloor distance A, the demonstration of thinner literal etc. fogs and can not realize high meticulous demonstration.Here, also can consider to use the situation of the thin glass substrate of thickness of slab t, but the glass substrate that thickness of slab t is thin is expensive, and, the manufacturing process that shows cholesteric liquid crystal display 100 at colour is less than under the situation corresponding to thin glass substrate, in order to make manufacturing process need the huge installation cost of cost corresponding to thin glass substrate, and the yield rate step-down is arranged and situation that cost uprises.
In addition, using under the situation of flexible base, board as the substrate 103,104,107,108,111,112 of reflective LCD 105,109,113, though make the flexible base, board attenuation easily, but the flexible base, board that is formed with nesa coating (ITO film) is expensive, and because flexible base, board has high flexibility, so be difficult to be formed uniformly liquid crystal cell (cell) gap of injecting liquid crystal, damage the homogeneity of liquid crystal display sometimes.
