Visible by technique scheme; A kind of LCD that the utility model provided; In the end of traditional LCD Polarizer, with on the contacted one side of glass substrate be not coated with the printing ink of designated color, utilize optical principle to realize on LCD, carrying out colour and show, can realize colored the demonstration thereby need not in this LCD, to add optical filter; And then reduced resource consumption, reduced the production cost that can realize the colored LCD that shows.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The composition structural scheme of mechanism of a kind of LCD that Fig. 1 is provided for the utility model embodiment.

Embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of LCD; On the end of this LCD polaroid, be coated with the printing ink of designated color, utilize optical principle, when utilizing this LCD to carry out numeral or image demonstration; Can realize the colored demonstration in zone; And need not in LCD, to add colored filter, and resource consumption is few, and cost is lower.

Referring to Fig. 1, be the structural representation of a kind of LCD of the utility model, this LCD comprises relative up and down layer glass substrate, this layer glass substrate is respectively upper strata glass substrate 11 and bottom glass substrate 12.

Upper strata glass substrate and bottom glass substrate vertical distribution; But this layer glass substrate is the neighbour not; On the basic interior surface opposing of this layer glass, be attached with layer of semiconductor transparent conductive film 2 respectively; That is to say that the one side that the upper strata glass substrate is relative with the bottom glass substrate is called the basic inside surface of glass, in two glass substrates opposing to one side be called outside surface.On the inside surface of upper strata glass substrate, be coated with layer of semiconductor transparent conductive film 2; In the inside surface of bottom glass substrate, also be coated with simultaneously layer of semiconductor transparent conductive film 2; This two-layer transparent conductive semiconductor film 2 is relative in this LCD; Simultaneously, in this two-layer transparent conductive semiconductor film, be filled with liquid crystal material 3.This liquid crystal material can be VA liquid crystal molecule in this area etc.

On the basic outside surface of layer glass, be provided with Polarizer (also can be called polaroid).According to these two bias plate position distributions these two Polarizers are called upper strata Polarizer 41 and bottom Polarizer 42 respectively; Wherein, Upper strata Polarizer 41 is arranged on the outside surface of upper strata glass substrate 11, and bottom Polarizer 42 is arranged on the outside surface of bottom glass substrate 12.Concrete, can this upper strata Polarizer be sticked on the outside surface of this upper strata glass substrate 11, this bottom Polarizer is sticked on the outside surface of this bottom glass substrate.

Show for the zone that can realize this LCD is colored, in this bottom Polarizer, with on the surface of bottom glass substrate joint be not coated with the printing ink 5 of designated color.In other words, the one side of this bottom Polarizer contacts with the bottom glass substrate, and with being called inside surface with this contacted surface of bottom glass substrate in the bottom Polarizer, another surface of this bottom Polarizer is called outside surface.The outside surface of this bottom polaroid exposes in the prior art, uncoated any film or other materials, and be coated with the printing ink 5 of designated color in the utility model on the outside surface of this bottom Polarizer.
