Show method, belong to photoelectric display technical field.
Background technology
In segment encode LCDs, VA (Vertical Alignment) vertical orientation type shows it is very general display
Pattern.There is the display that two methods realize this pattern：One kind is when making liquid crystal static using protrusion and unconventional upright
Formula, and it is static to be biased into some angle；It is horizontal then more fast to allow backlight to pass through when applying voltage by liquid crystal molecule and changing over
Speed, so, also because protrusion changes liquid crystal alignment, field-of-view angle can be made more wide so that the display time is greatly shortened
Extensively.Up to more than 160 degree in the increase at visual angle, the reaction time is foreshortened within 20ms.But this method can cause OFF
The state of some liquid crystal molecules and flexible non-stand-up under state, but tilted to some direction, under the transmitance that can so cause OFF state light
Drop, and then cause contrast to reduce, another method is that two layers of vertical orientation film design up and down on the inside of substrate is micron-sized
Minor groove, as shown in figure 1, this method liquid crystal molecule all keeps standing upright under OFF state, the light transmittance of OFF state reaches
Highest, and then contrast is improved, solve the problems, such as that first method is present, still, this method can cause to set groove
Position it is thick different from the box for being not provided with position, and then cause to show uneven, the present invention is directed to this problem, there is provided one kind
Solution.
The content of the invention
The purpose of the present invention is that the box to solve the position of the setting groove of prior art from being not provided with position is thick different, is led
The problem of causing display uneven, there is provided it is a kind of that there is wide viewing angle, and show uniform segment encode liquid crystal display.
The present invention adopts the technical scheme that to solve the above problems：A kind of wide viewing angle segment encode liquid crystal display of the present invention, bag

Well width is consistent with groove width, boss highly consistent with gash depth.
Further, the liquid crystal is dielectric anisotropy parameter, Δ ε<0 negative liquid crystal.
Further, the groove is set with boss interleaved.
The manufacture method of above-mentioned wide viewing angle segment encode liquid crystal display, specific steps include：
Step a, vertical orientation film is made on one piece of conducting glass substrate wherein, and according to specific on vertical orientation film
Distance interval, make the groove of specific width and depth；
Step b, according to the width and spaced design mask plate of groove；
Step c, one layer of photoresistance is coated on another piece of conducting glass substrate, the thickness of photoresist layer is identical with gash depth；
Step d, by mask plate designed in step b on conducting glass substrate of the surface coated with photoresistance is covered in,
It is put under ultraviolet and exposes；
Step e, conducting glass substrate of the surface coated with photoresistance after will be exposed, which is put into developer solution, to develop, and obtains table
Face carries the conducting glass substrate of boss, and the width of boss, height and interval and the groove on another conducting glass substrate
Width, depth and interval are corresponding；
Step f, vertical orientation film is made in one side of conducting glass substrate of the surface with boss with boss；
Step g, any one piece in two pieces of conducting glass substrates has the one side coating sealing frame of vertical orientation film, by two pieces
Conducting glass substrate contraposition fitting；
Step h, biaxial compensation film polaroid is pasted on the outside of the two pieces of conducting glass substrates posted.
Further, manufactured in step b mask plate when hollow out is made in position corresponding to groove, pass through light.
Further, the photoresistance used in the step e is negativity photoresistance.
The display methods of above-mentioned wide viewing angle segment encode liquid crystal display, it is specially：When being not added with voltage between upper and lower conducting glass substrate,
Liquid crystal molecule standing upright between upper and lower two layers of vertical orientation film, when the light that backlight is sent passes through liquid crystal cell, due to upper and lower
The polarization state of biaxial compensation film polaroid is vertical, eye-observation to dark-state；When applying voltage between upper and lower conducting glass substrate, liquid
Brilliant molecule is into swinging to all directions, and biaxial compensation film polaroid is compensated the light of all directions, the light that backlight is sent
During by liquid crystal cell, eye-observation on state of.
The beneficial effects of the invention are as follows：
In the existing VA type liquid crystal that micron order groove is made on upper conducting glass substrate or lower conducting glass substrate
On the basis of display, with photoresistance, position corresponding with groove makes width and groove width on another conducting glass substrate,
Height and gash depth identical boss, make the thickness of the liquid crystal in whole liquid crystal cell not change, reduce because of box thickness ununiformity
Even to cause display uneven, there is the problem of mura in screen surface.
