Embodiment
The 1st embodiment
At first, see also Figure 1A and 1B, be used for illustrating the reflective LCD panel construction of double-sided display of the present invention.Figure 1A is the top view that shows the reflective LCD panel construction of the double-sided display of the 1st embodiment according to the present invention, and Figure 1B is the sectional view that demonstration is broken along the 1B-1B among Figure 1A.The reflective LCD panel of double-sided display of the present invention is made up of a plurality of pixels (pixel) P that is arranged in array (array) mode, and those pixels P is by many gate lines (gate bus lines) 10 and 20 definition of many data lines (data bus lines).For the purpose of simplicity of illustration, the only corresponding pixel P of Figure 1A, 1B.
See also Figure 1A, 1B, each pixel P has one first viewing area 101 and one second viewing area 102, wherein this first viewing area 101 has overlapping part (an overlapping portion) 103 with this second viewing area 102, the width of this overlapping part 103 is preferably greater than 2 μ m, in order to avoid light leak.In the present embodiment, it is main viewing area (main displayarea) that first viewing area 101 can be used as, and can be used as be time viewing area (auxiliary display area) in second viewing area 102.This pixel P comprises following composition:
One first substrate 110 and one second substrate 120 of subtend mutually.Wherein this first substrate 110 for example is to include the substrate of glass of being used as a thin film transistor (TFT) (TFT) T that is pixel drive elements, this thin film transistor (TFT) T for example is bottom gate polar form TFT, Reference numeral 112 expression grids, Reference numeral 114 expression gate insulators, Reference numeral 116 expression semiconductor islands, Reference numeral S represents source electrode, and Reference numeral D representative drain electrode.In addition, this second substrate 120 for example is a substrate of glass.Because the manufacture method of thin film transistor (TFT) T has been prior art (for example being disclosed in United States Patent (USP) No. 6342935), at this for not obscure the feature of this case, so will not describe in detail.
One protective seam (protective layer) 130 is formed in this first substrate 110 and covers this thin film transistor (TFT) T.This protective seam 130 for example is oxide layer or organic insulator.
