In addition, U.S. Patent Publication No. 2001/0017679A1 discloses a kind of display panels 30, it is provided with a reflection horizon 39 below second polaroid 37, wear penetration region 35 it can be penetrated the further reflection of the incident light of backlight 38, and unlikely 34 in the zone that directly is reflected stops or is absorbed by second polaroid 37, shown in the c of path, but, inevitably, still have the part light source zone that is reflected and 34 stop and loss, shown in the d of path, and owing to need below polaroid 37, plate again one deck reflection horizon 39, so in manufacturing process, can produce problems such as contraposition is bad, thereby make the more difficult control of manufacturing process.
Summary of the invention
The purpose of this invention is to provide a kind of display panels that improves the light service efficiency, penetrance is increased and its reflectivity of unlikely reduction.
For reaching above-mentioned purpose and avoiding the shortcoming of prior art, the present invention discloses a kind of display panels, comprising:
One first substrate;
One second substrate;
One liquid crystal layer is arranged between this first substrate and second substrate; Reach a plurality of pixel capacitors, be arranged at the surface of this second substrate;
It is characterized in that this pixel capacitors comprises a plurality of projections, and each projection comprises:
(a) one first reflection horizon is arranged at the surface of this second substrate, and is that a hollow is circular-arc, and its center of arc place has an opening; And
(b) surface of this second substrate is located in one second reflection horizon, and is positioned at the opening below in this first reflection horizon.
Like this, the incident light of backlight can utilize the double reflection effect to wear from the opening in first reflection horizon and penetrate, and layer incident light that is stopped that originally be reflected is reflected to become once more penetrate light, to improve the light utilization rate.

Fig. 6 is the synoptic diagram of the principle of reflection of display panels of the present invention.
Embodiment
Fig. 4 is the sectional view of display panels 40 according to an embodiment of the invention, and it comprises one first substrate 41, one second substrate 42, a liquid crystal layer 43 and a plurality of pixel capacitors (scheming not shown).Liquid crystal layer 43 is arranged between this first substrate 41 and this second substrate 42, and each pixel capacitors comprises a plurality of projections 44.
Each projection 44 comprises one first reflection horizon 45 and one second reflection horizon 46.This first reflection horizon 45 is arranged at this second substrate, 42 surfaces, be one circular-arc, and its center of arc place has an opening 453, this first reflection horizon has a first surface 451 and a second surface 452, wherein this first surface 451 is used for the reflection environment light source, and this second surface 452 is used to reflect incident light source.This second reflection horizon 46 embeds these second substrate, 42 surfaces, and be positioned at this first reflection horizon 45 opening 453 under, this first reflection horizon 45 and second reflection horizon 46 are formed by the material with electric conductivity and high reflectance, and described material can be selected from: aluminium, silver, gold, neodymium and alloy thereof.The opening 453 in first reflection horizon 45 and the shape in second reflection horizon 46 do not limit, and the preferably is rectangle, circle or square.In addition, first reflection horizon 45 and 46 surfaces, second reflection horizon are smooth plane or concave surface, for use in reflection or optically focused.
Fig. 5 is the vertical view of display panels according to an embodiment of the invention, its opening 453 that utilizes each projection 44 is as penetrating region, can penetrate by opening 453 from the incident light of backlight like this, thereby can avoid the light source of prior art to reduce the shortcoming of light service efficiency because of the reflection horizon stops.
Fig. 6 is the principle of reflection synoptic diagram of display panels of the present invention.Wear from the opening 453 in first reflection horizon 45 through double reflection from the incident light of backlight and to penetrate.By path f and g as can be known, the incident light from backlight can penetrate through second reflection horizon 46 reflection for the second time and from opening 453 through 46 surfaces, second surface 452 first reflection to the second reflection horizon in first reflection horizon 45 again.Like this, in the prior art, because of reflector space stops the incident light of loss, can further be reflected to form penetrates light, and like this, the present invention can increase and penetrates efficient and reach more than three times.
