Abstract

A fabricating method of display panel is provided. A first substrate having display area and non-display area is provided. A pixel array and a spacer layer are respectively formed in the display area and non-display area by forming many first strip electrodes parallel to each other and on the substrate, by forming an organic function layer on the substrate and covering the first strip electrodes, and by forming many second strip electrodes parallel to each other and on the organic function layer. An extension direction of the first strip electrodes is different to that of the second strip electrodes. The spacer layer surrounds the display area. A sealant is formed in the non-display area, and the spacer layer is disposed between the sealant and the pixel array. A second substrate is arranged above the first substrate, and the first substrate and the second substrate are fixed by using the sealant.

Claims (26)

1. A display panel, comprising:

a first substrate, wherein the first substrate has a display area and a non-display area and the display area has a pixel array, wherein the pixel array comprises:

a plurality of first strip electrodes parallel to each other and on the substrate;

an organic function layer on the substrate and covering the first strip electrodes; and

a plurality of second strip electrodes parallel to each other and on the organic function layer, wherein an extension direction of the first strip electrodes is different to that of the second strip electrodes;

a spacer layer in the non-display area, wherein the spacer layer surrounds the display area, a material of the spacer layer comprises at least one materials selected from the group consisting of the first strip electrodes, the organic function layer and the second strip electrodes;

a second substrate disposed opposite to the first substrate; and

a sealant between the first and second substrates and in the non-display area of the first substrate, wherein the spacer layer is disposed between the sealant and the pixel array.

2. The panel as claimed in claim 1 , wherein a material of the spacer layer is a material selected from the group consisting of the first strip electrodes, the organic function layer and the second strip electrodes.

3. The panel as claimed in claim 1 , wherein the organic function layer comprises:

a hole transmission layer on the substrate, and the hole transmission layer covers the first strip electrodes;

a luminescent layer on the hole transmission layer; and

an electron transmission layer on the luminescent layer.

4. A fabricating method of a display panel, comprising:

providing a first substrate, wherein the first substrate has a display area and a non-display area;

forming a pixel array in the display area, and forming a spacer layer in the non-display area, wherein the spacer layer surrounds the display area, the spacer layer is formed simultaneously in at least one of the steps of the formation method of the pixel array, and the formation method of the pixel array comprises:

forming a plurality of first strip electrodes parallel to each other and on the substrate;

forming an organic function layer on the substrate and covering the first strip electrodes; and

forming a plurality of second strip electrodes parallel to each other and on the organic function layer, wherein an extension direction of the first strip electrodes is different to that of the second strip electrodes;

forming a sealant in the non-display area, wherein the spacer layer is disposed between the sealant and the pixel array;

providing a second substrate; and

assembling the second substrate and the first substrate, wherein the first substrate and the second substrate are fixed by the sealant.

5. The fabricating method as claimed in claim 4 , wherein the formation method of the organic function layer comprises:

forming a hole transmission layer on the substrate, and the hole transmission layer covers the first strip electrodes;

forming a luminescent layer on the hole transmission layer; and

forming an electron transmission layer on the luminescent layer.
