Then sub-pixel is blue subpixels B.Vertically, be connected three red sub-pixel R, green
Sub-pixels G and blue subpixels B constitute a pixel 1.
So, the spring song of horizontal direction to the display panels after box is made extremely by external force
During required radian, although it is possible that array base palte 20 and color membrane substrates 30 are in the horizontal direction
Upper offset, but owing in the horizontal direction, the sub-pixel of same row is same color sub-picture
Element, thus also can guarantee that the color of the light sent from each sub-pixel is for red or for green
Color, or be all blue, and then the problem that colour mixture can be avoided.
Embodiment six, first substrate is array base palte 20, and second substrate is base plate for packaging 50.
Based on this, with reference to shown in Fig. 4 a and Fig. 4 b, form the array of described curved face display panel
Substrate 20 includes: form grid line 21 and data wire 22 on the first substrate；Wherein, grid line
21 (the present embodiment is as a example by horizontal direction) extensions in a second direction, data wire 22 is along first
Direction (the present embodiment is as a example by vertical direction) extends；Grid line 21 and data wire 22 intersection limit
The region of stator pixel.The region of the most corresponding described sub-pixel forms switch crystal
Pipe 23, drive transistor 25, (the present embodiment with the first electrode for anode 26 is anode 26
Example), negative electrode 27 and the organic material functional layer 28 between anode 26 and negative electrode 27；
Switching transistor 23 and driving transistor 25 all include grid, gate insulation layer, semiconductor active
Layer, source electrode and drain electrode, grid line 21 electrically connects with the grid of switching transistor 23, data wire
22 electrically connect with the source electrode of switching transistor 23, the drain electrode of switching transistor 23 and driving crystalline substance
The grid electrical connection of body pipe 25, drives the source electrode of transistor 25 to electrically connect with voltage source Vdd,
The drain electrode driving transistor 25 electrically connects with anode 26；Organic material functional layer can include electricity
Sub-transport layer and hole transmission layer and white light-emitting layer therebetween, certainly can also root
According to needs, electron injecting layer and hole injection layer are set.
The base plate for packaging 50 forming described curved face display panel includes: corresponding on the second substrate
The region of described sub-pixel forms the first color filter pattern, and (the present embodiment is with red filter pattern
As a example by 32), the second color filter pattern (the present embodiment is as a example by green filter pattern 33)
With the 3rd color filter pattern (the present embodiment is as a example by blue filter pattern 34)；Adjacent son
Pixel region is spaced by black matrix 31, i.e. black matrix 31 is formed at sub-picture described in arbitrary neighborhood
Between element, also (include switching transistor 23 with the transistor in described sub-pixel and drive crystalline substance
Body pipe 25) corresponding.Wherein, red filter pattern 32, green filter pattern 33 and blue filter
Light pattern 34 arranged in rows the most in the horizontal direction；Vertically, red filter pattern 32,
Green filter pattern 33 and blue filter pattern 34 are arranged in order.
On this basis, after array base palte 20 and base plate for packaging 50 encapsulate, corresponding every height
The region of pixel just forms corresponding sub-pixel.Wherein, red filter pattern is included when sub-pixel
When 32, then this sub-pixel is red sub-pixel R；When sub-pixel includes green filter pattern 33
Time, then sub-pixel is green sub-pixels G；When sub-pixel includes blue filter pattern 34,
Then sub-pixel is blue subpixels B.Vertically, be connected three red sub-pixel R, green
Sub-pixels G and blue subpixels B constitute a pixel 1.
So, the spring of the horizontal direction of the OLED display panel after encapsulation is made by external force
During bent extremely required radian, although it is possible that array base palte 20 and base plate for packaging 50 are in level
Offset on direction, but owing in the horizontal direction, the sub-pixel of same row is same color
Sub-pixel, thus also can guarantee that the color of the light sent from each sub-pixel for red or
For green, or it is all blue, and then the problem that colour mixture can be avoided.
Preferably, with reference to shown in Fig. 5, adjacent two row's sub-pixels constitute described sub-pixel group.Base
