Abstract

The present invention provides a reflection type color liquid crystal display device which can maintain the homogeneity of liquid crystal display and can reduce the parallax and its manufacturing method. The reflection type color liquid crystal display device has a light absorbing layer (11) and a red reflect LCD (15), a green reflect LCD (19) and a blue reflect LCD (23) cascaded on the light absorbing layer (11) in sequence. These reflect liquid crystal displays (15, 19 and 23) have plural glass base plates (13 and 14, 17 and 18, 21 and 22) and liquid crystal layers (12, 16 and 20) formed among the plural glass base plates (13 and 14, 17 and 18, 21 and 22). At least two surfaces of the plural glass base plate surfaces between the first liquid crystal layer (12) disposed nearest to the light absorbing layer (11) and the second liquid crystal layer (20) disposed farthest to the light absorbing layer (11) are grinded; and the maximum value of the parallax B (mm) represented by the follow formula is lower than 0.51 mm. B=A x tan(arcsin(sinTheta / n) x cosTheta); Theta: view angle; A: distance (mm) between reflect liquid crystal layer; n: the refractivity of the grinded glass base plate.

Description

technical field

[0001] The present invention relates to a reflective color liquid crystal display device and a manufacturing method thereof, in particular to a color display cholesteric liquid crystal display formed by stacking reflective liquid crystal displays (reflective LCDs) and a manufacturing method thereof. Background technique

[0002] A color display cholesteric liquid crystal display is constructed by laminating reflective liquid crystal displays (reflective LCD) that select and reflect a predetermined wavelength. For example, as shown in FIG. 9 , a color display cholesteric liquid crystal display 100 is equipped with: a black light absorbing layer 101; The red reflective liquid crystal layer 102 of the reflective color; the green reflective LCD 109 laminated on the red reflective LCD 105, and the green reflective liquid crystal layer 106 showing the green reflective color is formed between the substrates 107 and 108; and the green reflective LCD 109 laminated on ...
