BACKGROUND

(a) Field of Disclosure

The present disclosure of invention relates to a liquid crystal display, and more particularly, to a liquid crystal display having increased transmittance and reduced deterioration of a display quality.

(b) Description of Related Technology

The liquid crystal display (LCD) is currently one of the most widely used types of flat panel displays. Generally the LCD is a display device used for adjusting magnitude of a transmitted therethrough light by applying a voltage between electrodes so as to rearrange liquid crystal molecules of a liquid crystal layer and thus impart desired optical effects (e.g., modulated polarity) to the transmitted through light.

The liquid crystal display has a merit in that it is easy to form as striped or otherwise matrix like repeated groups of differently colored subpixels, but it has a drawback in that a lateral visibility of its image is lower than a frontal visibility. Accordingly, various methods of arranging and driving liquid crystal to have different domains have been developed to overcome the drawback. A liquid crystal display where a pixel electrode and a common electrode are formed on one substrate has received attention as a method of implementing a wide viewing angle.

In the liquid crystal display, at least one of two field generating electrodes of the pixel electrode and the common electrode has a plurality of cutouts for thereby defining different liquid crystal domains, and a plurality of branch electrodes defined by a plurality of cutouts.

Meanwhile, if a fluidic pressure wave is generated in one of the cutouts, for example due to impact applied from the outside of the liquid crystal display, the wave spreads easily along the channel of a straight cutout and a corresponding irregular behavior of liquid crystal molecules occurs where the irregular behavior of the liquid crystal molecules easily spreads along the entire length of the cutout of the field generating electrode. It is possible to prevent such easy spreading (propogation) of irregular pattern behavior of the liquid crystal molecules by variously forming angles in pattern of the cutouts (e.g., as measured relative to a vertical standard line).

However, an aperture size of each pixel area of the liquid crystal display may be reduced due to introduction of such angles and; as a resolution of the liquid crystal display is increased by decreasing the sizes of all pixel areas, a corresponding aperture transmittance factor of the liquid crystal display is deteriorated by such forming of the angle between the cutout and the vertical standard line where data lines and gate lines of the device extend according to straight lines and switching elments (TFTs) are disposed in corner portions of such pixel unit cell structures.

It is to be understood that this background of the technology section is intended to provide useful background for understanding the here disclosed technology and as such, the technology background section may include ideas, concepts or recognitions that were not part of what was known or appreciated by those skilled in the pertinent art prior to corresponding invention dates of subject matter disclosed herein.

SUMMARY

The present disclosure of invention provides a liquid crystal display capable of having a high resolution (e.g., 200 or more pixel areas per inch) in which the basic repeat pattern of pixel electrodes, common electrode and switching element is structured as bounded by two identical parallelograms, one flipped vertically and stacked with its base directly on top of the roof of its twin and then a rectangle with a same width as the base stacked directly under or on top of the two parallelograms, where the switching element is substantially contained in the rectangle. This forms a repeated unit cell and then angles of inclined straight edges within cutout areas of the unit cell are adjusted so as to simultaneously provide for reduced degradation to image quality due to extrnal pressure shocks and increased transmittance of backlighting light through the respective unit cells.

In one embodiment, two field generating electrodes are formed on a same one substrate and at least one of the two field generating electrodes is patterned to have a muliply-bent cutout, such that the multple bends along the fluid flow directing channel of the cutout prevent direct propogation of fluid pressure waves linearly along the full length of the cutout and thus irregular behaviors of liquid crystal molecules according to external pressures are inhibited from easily moving along the entire cutout. The basic two parallelograms plus rectangle shape and specific bend angles of the cutouts also help to prevent deterioration of a backlighting transmittance efficiency of the liquid crystal display.

An exemplary embodiment provides a liquid crystal display including: a first substrate, a gate line disposed on the first substrate and substantially extending parallel to a horizontal reference line (X axis), and a plurality of repeated pixel unit cells disposed on the first substrate and each including a first field generating electrode and a second field generating electrode with an insulating layer interposed therebetween, wherein one of the first and second field generating electrodes has a plurality of cutouts, where the plurality of cutouts each includes a first inclined edge portion forming a first angle with a vertical reference line (Y axis), the latter forming an angle of 90° with the horizontal reference line (X axis) of the gate line and where each cutout further includes a second inclined edge portion forming a second angle with the vertical reference line (Y axis) that is different from the first angle, where a ratio of a vertical length of the first inclined edge portion to a vertical length of the cutout is about 80% or more but less than 100%, and density of the plurality of pixels is about 200 PPI (pixels per inch) or more.

A value obtained by multiplying the ratio of the vertical length of the second inclined edge portion to the vertical length of the cutout or the ratio of the vertical length of the third inclined edge portion to the vertical length of the cutout by the vertical length of the pixel is about 5 μm or less.

The horizontal length of the pixel unit cell may be about 40 μm or less and a vertical length thereof may be about 120 μm or less.

First, referring toFIGS. 1 and 2, the liquid crystal display according to the first exemplary embodiment includes a lower display panel100and a spaced apart upper display panel200facing the lower panel and a liquid crystal material layer3interposed therebetween.

More specifically, the highly dense matrix of pixel areas may have a resolution in at least one direction of about 200 PPI (pixel areas pr inch) or greater. That is, about 200 or more pixels may be included in a region of about 1 inch as measured in at least one of, but preferably both of orthoganal major axes (e.g., horizontal and vertical) of the liquid crystal display. Further, the horizontal axis length L1of one pixel area according to the exemplary embodiment may be about 40 μm or less and the vertical axis length L2thereof may be about 120 μm or less. Three such pixel areas, each having the same 1:3 aspect ratio may be ganged together to define a substantially square luminance providing region of about 120 μm by 120 μm or less where the three, so ganged together pixel areas have respective different colors such as Red, Green and Blue which in unison can create perception of a white light. Rather than being perfectly square, the substantially square luminance providing region may include a shape such as that of two identical parallelogroms joined at their corresponding boundaries to one another with one of the parallelogroms being flipped upside down. Herein, as shown in the drawings, the horizontal length L1of the pixel area is an X-axis interval between same vertical center portions of the two adjacent data lines171, and the vertical length L2of the pixel is a Y-axis interval between same horizontal center portions of two adjacent gate lines121.

The first bent portions of the data line171may meet each other in so-called, central or middle region of the respective pixel areas to form corresponding V shapes. In one embodiment, the data line171additionally has periodically repeated second bent portions that are bent so as to form a predetermined angle with the first bent portions where the second bent portions may be further included in the middle regions of the corresponding pixel regions.

The liquid crystal molecules of the liquid crystal layer3are arranged so that a long axis direction thereof is parallel to the display panels100and200, and the liquid crystal layer has a twisted spiral structure where the direction thereof is 90° from the rubbing direction of the alignment layer of the lower display panel100to the upper display panel200.

Referring toFIG. 5in more detail, the liquid crystal display according to the present exemplary embodiment is similar to the liquid crystal display according to the exemplary embodiment shown inFIGS. 1 and 2. A detailed description of the similar constituent elements will be omitted.

However, the liquid crystal display according to the present exemplary embodiment further includes a reference voltage supplying line131formed of the gate conductor like the gate line121unlike the liquid crystal display according to the exemplary embodiment shown inFIGS. 1 and 2. The reference voltage supplying line131transfers a predetermined reference voltage (Vcom) to corresponding reference electrode portions, and it includes a respective extension portion for connection with the reference electrode270of each respective pixel area. The reference voltage line131may extend parallel to the gate line121and be formed of the same material(s) as that of the gate line121.

The reference electrode270may be physically and electrically connected through the second contact hole138formed in the first passivation layer180nand the second passivation layer180qto the reference voltage supplying line131to thereby receive a common voltage (Vcom) having a predetermined size from the reference voltage line131.

The reference electrodes270of respective pixel areas may be connected to each other to receive the reference voltage from the reference voltage application portion disposed in the outside of the display region, but may be additionally connected to the reference voltage line131to receive the reference voltage, thus preventing the reference voltage from being reduced in the display region due to the highere resistivity of the material of the reference electrode270taken alone.

Like the aforementioned liquid crystal display according to the exemplary embodiment described with reference toFIGS. 1 and 2, the pixel electrode191of the liquid crystal display according to the present exemplary embodiment includes the first cutout92having the same shape as the basic electrode199described below with reference toFIG. 6and a plurality of first branch electrodes192according thereto. The first cutouts92of the pixel electrode191includes the main branch portion forming the first angle θ1with the vertical reference line (reference line extending in a y direction) forming 90° with the extension direction (x direction) of the gate line121, the center portion forming the second angle θ2with the vertical reference line, and the edge portion forming the third angle θ3with the vertical reference line. The second angle θ2and the third angle θ3may be larger than the first angle θ1. The vertical length of the main branch portion of the second cutout272of the reference electrode270may be about 80% or more of the vertical length of the cutout. Here, the vertical length is measured in a direction parallel to the vertical reference line (reference line extending in a y direction). The vertical length of the center portion may be about 6% to about 13% of the vertical length of the cutout and the vertical length of the edge portion may be about 0% to about 10% of the vertical length of the cutout. Further, the value obtained by multiplying the sum of the ratio of the vertical length of the center portion to the vertical length of the second cutout272of the reference electrode270and the ratio of the vertical length of the edge portion to the vertical length of the cutout by 10 and then dividing the multiplied value by PPI of the liquid crystal display may be about 1 or less. Further, the value obtained by multiplying the sum of the ratio of the vertical length of the center portion to the vertical length of the second cutout272of the reference electrode270and the ratio of the vertical length of the edge portion to the vertical length of the cutout by the vertical length of one pixel may be about 20 μm or less. Further, the value obtained by multiplying the ratio of the vertical length of the center portion to the vertical length of the second cutout272of the reference electrode270by the vertical length of one pixel may be about 5 μm or less. Further, the value obtained by multiplying the ratio of the vertical length of the edge portion to the vertical length of the second cutout272of the reference electrode270by the vertical length of one pixel may be about 5 μm or less.

Next, a basic patterned electrode199corresponding to one of the field generating electrodes (either the pixel electrode if it is patterned or the reference electrode if it is patterned) of the liquid crystal display according to an exemplary embodiment will be described with reference toFIG. 6.

Referring toFIG. 6, the cutout of the basic electrode of the field generating electrode of the liquid crystal display according to the exemplary embodiment includes the main branch portion MS (interposed between central section CS and end section ES and) forming the first angle θ1with the vertical reference line (reference line extending in a y direction) forming 90° with the extension direction (x direction) of the gate line121. It further includes the center portion CS forming the second angle θ2with the vertical reference line, and the edge portion ES forming the third angle θ3with the vertical reference line. The second angle θ2and the third angle θ3may be larger than the first angle θ1. For example, the first angle θ1may be about 5° to about 20°, and the second angle θ2may be about 40° to about 50°.

Likewise, the cutout of the basic electrode of the field generating electrode is formed so as to further include the center portion CS and the edge portion ES having the angle that is larger than the angle of the main branch portion MS with respect to the vertical reference line, in addition to the main branch portion (MS). That is, the cutout is bent at a large angle at a boundary portion of the main branch portion MS and the center portion (CS), and the cutout is bent at a large angle at a boundary portion of the main branch portion MS and the edge portion (ES). Therefore, in a case where external pressure and the like are applied from the outside (e.g., by a user's finger) to press on the center portion CS and/or to the edge portion (ES), it is possible to prevent a spreading of the pressure-induced irregular positions of liquid crystal molecules directly to the main branch portion (MS). Specifically, irregular behavior of the liquid crystal molecules occurring at the center portion CS and the edge portion ES is not moved in a straight line to and along the boundary portion with the main branch portion MS that is bent at a large angle relative to the direction of the externally generated pressure wave(s). Therefore, it is possible to prevent a bruising phenomenon according to external pressures and the like.

As described above, the liquid crystal display according to the exemplary embodiments may have resolution of about 200 PPI or more. That is, about 200 or more pixels may be included in a region about 1 inch in each dimension in the liquid crystal display. Further, the horizontal length of one pixel of the liquid crystal display according to the exemplary embodiment of the present invention may be about 40 μM or less and the vertical length thereof may be about 120 μm or less.

The vertical length of the main branch portion MS of the cutout of the basic electrode of the field generating electrode may be about 80% or more of the vertical length of the cutout, the vertical length of the center portion CS may be about 6% to about 13% of the vertical length of the cutout, and the vertical length of the edge portion ES may be about 0% to about 10% of the vertical length of the cutout.

The vertical length of the center portion CS of the cutout and the vertical length of the edge portion ES of the cutout may be about 5 μm or less, and the vertical length of the cutout may be about 100 μm.

Further, the value obtained by multiplying the sum of the ratio (%) of the vertical length of the center portion CS to the vertical length of the cutout and the ratio (%) of the vertical length of the edge portion ES to the vertical length of the cutout by 10 and then dividing the multiplied value by PPI of the liquid crystal display may be about 1 or less.

Further, the value obtained by multiplying the sum of the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout by the vertical length of one pixel may be about 20 μm or less.

Further, the value obtained by multiplying the ratio of the vertical length of the center portion CS to the vertical length of the cutout by the vertical length of one pixel may be about 5 μm or less.

Further, the value obtained by multiplying the ratio of the vertical length of the edge portion ES to the vertical length of the cutout by the vertical length of one pixel may be about 5 μm or less.

Likewise, light transmittance through the pixel area apertures of the liquid crystal display may be increased by increasing the vertical length of the ratio of the main branch portion MS of the cutout of the field generating electrode to the vertical length of the cutout and reducing the ratio of one or both of the center portion CS and the edge portion ES thereto.

Next, the transmittance of the liquid crystal display according to Experimental Examples will be described with reference to Tables 1 and 2 andFIG. 7.

That is, in the present Experimental Example, the light-passing transmittance was measured while the resolution of the liquid crystal display, for example, PPI, that is, the total number of pixels disposed in the region about 1 inch in each dimension in the liquid crystal display, the horizontal length and the vertical length of the pixel, the vertical length of the cutout, the vertical length of the center portion CS of the cutout, the vertical length of the edge portion ES of the cutout and the like were changed, and a result thereof is described in the following Table 1. For example, the transmittance was measured, in similar manner to how done for a known liquid crystal display, in the cases where the ratio of the vertical length of the center portion CS of the cutout and the ratio of the vertical length of the edge portion ES to the evertical length (L) of the cutout were formed (Case A1, Case A2, and Case A3), and like the liquid crystal display according to the exemplary embodiment of the present invention, in the cases where the ratio of the vertical length of the center portion CS of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout were adjusted (Case B1, Case B2, Case B3, Case B4, and Case B5). All other conditions were the same. When the same fluidic disturbance pressure was applied to all the liquid crystal displays manufactured in the present Experimental Examples, it was found that a bruising phenomenon does not occur.

Referring to the aforementioned Table 1, it can be seen that as compared to the cases where the ratio of the vertical length of the center portion CS of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length (L) of the cutout are relatively large, for example, the ratio of the edge portion ES of the cutout is about 7.5% and the ratio of the center portion CS is about 15% or more (Case A1, Case A2, and Case A3), like the liquid crystal display according to the exemplary embodiment, in the cases where the ratio of the center portion CS of the cutout and the ratio of the edge portion ES to the entire length of the cutout are adjusted (Case B1, Case B2, Case B3, Case B4, and Case B5), the transmittance of the liquid crystal display is increased even though PPI of the liquid crystal display is large (e.g., ≧200 PPI). That is, it can be seen that like the liquid crystal display according to the exemplary embodiment, if the ratio of the vertical length of the center portion CS of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout are adjusted, the transmittance of the liquid crystal display is increased even though the liquid crystal display is formed to have high resolution (e.g., ≧200 PPI).

Likewise, it can be seen that in the liquid crystal display according to the exemplary embodiment, it is possible to prevent a bruising phenomenon according to external pressure and prevent a reduction in transmittance of the liquid crystal display.

In the present Experimental Example, the value A obtained by multiplying the sum of the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout by 10 and then dividing the multiplied value by PPI of the liquid crystal display, the value B obtained by multiplying the sum of the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout and the vertical length of one pixel, the value C obtained by multiplying the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the vertical length of one pixel, and the value D obtained by multiplying the ratio of the vertical length of the edge portion ES to the vertical length of the cutout and the vertical length of one pixel were calculated, and are described in the following Table 2.

Referring to Table 2, it can be seen that like the liquid crystal display according to the exemplary embodiment of the present invention, in the case where the value obtained by multiplying the sum of the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout by 10 and then dividing the multiplied value by PPI of the liquid crystal display is about 1 or less (Case B1, Case B2, Case B3, Case B4, and Case B5), the transmittance is increased.

Further, it can be seen that like the liquid crystal display according to the exemplary embodiment of the present invention, in the case where the value obtained by multiplying the sum of the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the ratio of the vertical length of the edge portion ES to the vertical length of the cutout and the vertical length of one pixel is about 20 μm or less (Case B1, Case B2, Case B3, Case B4, and Case B5), the transmittance is increased.

Further, it can be seen that like the liquid crystal display according to the exemplary embodiment, in the case where the value obtained by multiplying the ratio of the vertical length of the center portion CS to the vertical length of the cutout and the vertical length of one pixel is about 5 μm or less (Case B1, Case B2, Case B3, Case B4, and Case B5), the transmittance is increased.

Further, it can be seen that like the liquid crystal display according to the exemplary embodiment of the present invention, in the case where the value obtained by multiplying the ratio of the vertical length of the edge portion ES to the vertical length of the cutout and the vertical length of one pixel is about 5 μm or less (Case B1, Case B2, Case B3, Case B4, and Case B5), the transmittance is increased.

Next, the bruising phenomenon of the liquid crystal display according to an Experimental Example of the present invention will be described with reference toFIG. 7parts (a) and (b).FIG. 7is an electronic microscope picture showing a result of transmittance of a portion of the liquid crystal display according to an Experimental Example of the present invention.

In the present Experimental Example, the second angle θ2was changed in two cases (Case A1 and Case B4) in the Experimental Example described with reference to Table 1. Specifically, in the case (7a) where the vertical length of the center portion CS of the cutout of the field generating electrode is about 10 μm and the second angle θ2is about 25° (Case A1) like the known liquid crystal display, and in the case (7b) where the vertical length of the center portion CS of the cutout of the field generating electrode is about 5 μm and the second angle θ2is about 45° (Case B4) like the liquid crystal display according to the exemplary embodiment of the present invention, after external pressures having the same magnitude are applied, the center portion of the cutout is observed by an electronic microscope, and the respective results thereof is shown inFIG. 7parts (a) and (b).

More specifically,FIG. 7(a)shows the result of the present Experimental Example (Case A1), andFIG. 7(b)shows the result of the present Experimental Example (Case B4).

Referring toFIG. 7, when the same external pressure is applied, it can be seen that in the case of the exemplary embodiment of the present invention (Case B4), like the case of a known liquid crystal display (Case A1), a transmittance deterioration portion according to irregular behavior of liquid crystal is formed only at the center portion CS of the cutout but is not diffused to the main branch portion MS of the cutout. Likewise, it can be seen that the liquid crystal display according to the exemplary embodiment of the present invention can prevent movement of irregular behavior of the liquid crystal molecules according to the external pressure along the cutout and also prevent deterioration in transmittance in the liquid crystal display having high resolution.
