Embodiment 1

[0028] Figure 1A A top view showing an embodiment of the present invention applying a transparent electrode pattern with radial slits (fine slit) on the reflective region structure of the vertically aligned reflective TFT-LCD structure and the transflective TFT-LCD, wherein The transparent electrode pattern 13 can be made of Indium Tin Oxide (ITO, Indium Tin Oxide) material, and the slits 131 can be formed by etching. The width of the slits 131 and the distance between them are about 3-5 μm. Figure 1B Show a top view of the upper substrate transparent electrode corresponding to the position of the transparent electrode pattern, wherein a hole is formed at the center of the transparent electrode 21 or a bump (protrusion) 211 is made on the electrode there, and the transparent electrode 21 Usually an ITO electrode, the bump is made of a non-conductive material. Figure 1C It is a plan view of the combination of the upper substrate transparent electrode 21 and the transparent e...

Embodiment 2

[0036] Please refer to Figure 4 , which shows the cross-sectional structure of another embodiment of the transflective TFT-LCD unit pixel with transparent electrode patterns of the present invention. The difference between this embodiment and the first embodiment is that a hole 22' is formed at the center of the transparent electrode 21 of the upper glass substrate 20 corresponding to the position of the transparent electrode pattern 13. The color filter material under 20 leaks from the hole 22' to the liquid crystal layer 15, and a transparent protective film (not shown) can be formed between the transparent electrode 21 and the color filter (not shown). In this way, a transflective TFT-LCD with a multi-domain vertical alignment mode structure in the reflective region is also formed. When a voltage is applied to the pixel electrodes of the liquid crystal display, four-fold domains are generated and it is a continuous The type of the region.

Abstract

The invention is a contrast and reacting speed-enhanced multizone vertical allocation transistor LCD, especially a reflecting structure as well as semipermeable reflecting film transistor LCD structure in multizone vertical allocation mode in the reflecting area. By making a transparent flat layer and transparent electrode pattern with radioactive fine slits on the whole reflecting board with raised point structure and better forming a hole or protrusion in the middle of the transparent electrode on the top basal plate corresponding to the transparent electrode pattern, it can not only make the liquid crystal layer of the vertical allocation reflecting TFT-LCD or the reflecting area of the semilpermeable semireflecting TFT-LCD form multiple areas, where the liquid crystal molecules are arranged stably, accordingly making the LCD have broader visual angle, and able to reduce light leakage and enhancing contrast effect.

Description

technical field [0001] The present invention relates to a reflective thin film transistor liquid crystal display with a multi-domain vertical alignment mode (Multi-Domain Vertical Alignment Mode; MVA) and a semi-transparent semi-reflective thin film transistor liquid crystal display with an MVA mode in the reflection area, especially a kind of In reflective thin film transistor liquid crystal display and in the reflective area of ​​transflective semi-reflective thin film transistor liquid crystal display, a transparent electrode pattern structure with radial slits (fine slit) is formed on a transparent flat layer to improve contrast and reaction speed. Background technique [0002] With the rapid progress of thin film transistor manufacturing technology, liquid crystal displays with the advantages of thinness, power saving, and no radiation are widely used in calculators, personal digital assistants (PDAs), watches, notebook computers, digital cameras and In various electro...
