Description
Technical field
The present invention relates to a kind of LCD and manufacture method thereof, relate in particular to a kind of fixedly LCD and manufacture method thereof in the hole of chock insulator matter of on oriented layer, being provided for, belong to electronic equipment and make the field.
Background technology
Water ripple phenomenon (Touch Mura) is that the surface when display panels is subjected to external force to do the time spent, the turn white bad phenomenon of problem of display image occurs in stressed position.The main cause that produces water ripple phenomenon is: do the time spent when the surface of display panels is subjected to external force, deformation can take place in display panels, and when external force was enough big, color membrane substrates and array base palte under external force relative displacement can take place; Because the thickness difference of each layer of deposition on the array base palte, this displacement makes the situation of replacing of chock insulator matter and array base palte change; When external force was cancelled, owing to replace the variation of situation, the feasible relative displacement that the chock insulator matter of deformation takes place was difficult to recover.Therefore, in the bigger position of displacement, black matrix can not shelter from light, will produce water ripple phenomenon.
A kind of method of eliminating water ripple phenomenon is the thickness that increases glass substrate in the prior art, strengthen the thickness of array base palte and color membrane substrates, thereby alleviate the deformation problems that takes place when stressed, reduce the relative displacement degree of array base palte and color membrane substrates, and then reduce the incidence of water ripple phenomenon.But the lightening developing direction of this method and present LCD is disagreed, because the weight and volume of starting material and product increases, has also improved transportation cost.
The another kind of method of eliminating water ripple phenomenon is in the prior art: in process of manufacture, the size shape error of array of controls substrate and color membrane substrates makes the array base palte of box and the size shape of color membrane substrates is reached unanimity.But this method need increase the test quantity and the number of times of size positions skew, has increased the number of times of doing over again, and has improved production cost and handling cost.
In addition, because a glass substrate comprises several screens, above-mentioned two kinds of methods are only controlled whole substrate of array base palte and color membrane substrates and are improved, be not at each concrete on substrate screen, because the size and the positional precision deviation of each screen on glass substrate are all not quite identical, above-mentioned water ripple phenomenon improve effect and not obvious.
Summary of the invention
The object of the present invention is to provide a kind of LCD and manufacture method thereof, can prevent to produce water ripple phenomenon, and reduce cost, enhance productivity.
The invention provides a kind of manufacture method of LCD, comprise forming array base palte, color membrane substrates and chock insulator matter, wherein also comprise:
The invention provides a kind of LCD, comprise array base palte, color membrane substrates and chock insulator matter, wherein, be provided with the hole on the oriented layer of replacing with described chock insulator matter, described chock insulator matter is fastened onto in the described hole.
The present invention is by being provided with the hole on the oriented layer of replacing with chock insulator matter, make chock insulator matter be fastened onto in the hole, even when being subjected to external impacts, because the cylindrical spacer of each pixel is fixed by the hole, do not produce displacement between array base palte and the color membrane substrates, prevent to produce water ripple phenomenon, thereby improved product quality; Simultaneously, do not need to increase the thickness of glass substrate, reduced the test and the number of times of doing over again yet, reduced cost, improved production efficiency.
