1. A flexible display device comprising:
- (a) a flexible substrate having a first and second surfaces;
(b) a plurality of display pixels arranged in a form of rows and columns on the first surface of the substrate;
(c) a plurality of first parallel grooves in the first surface of the substrate, the first groove being formed in between adjacent two rows or columns of the display pixels, thereby providing flexibility to the display device and, at the same time, minimizing the propagation of mechanical stress caused when the display device is bent or rolled; and
(d) a plurality of connection lines for electrically interconnecting the plurality of display pixels wherein part of the connection lines is provided on the second surface of the substrate.

Abstract
A flexible display device (10) is disclosed. The flexible display device comprises a flexible substrate (12), a number of display pixels (14) arranged in a form of rows and columns on the surface of the substrate, a number of grooves (16) in the surface of the substrate each of which is formed in between adjacent two rows or columns of the display pixels (14), and connection lines (18) for electrically interconnecting the plurality of display pixels (14), thereby providing flexibility to the display device and, at the same time, minimizing the propagation of mechanical stress caused when the display device is bent or rolled. A method of manufacturing the display device is also disclosed.

7. A method of manufacturing a flexible display device, the method comprising the steps of:
-
(a) providing a flexible substrate having a first and second surface; (b) forming a plurality of first parallel grooves in the first surface of the substrate, each adjacent two parallel grooves defining a pixel area therebetween; (c) providing a plurality of display pixels on the pixel area such that the display pixels are arranged in a pattern of rows and columns; and (d) providing a plurality of connection lines to electrically interconnect the display pixels comprising; (i) providing a first connection line to connect the first surface with the second surface of the substrate; and (ii) providing a second connection line on the second surface of the substrate such that the first connection line serves to electrically connects the display pixel on the first surface to the second connection line on the second surface. - View Dependent Claims (8, 9, 10, 11)
