Display device with support member having a dent
View Patent ↗In a display device which includes a display panel in which a plurality of pixels are arranged on a substrate two-dimensionally and which is configured to display an image thereon, and a support member which supports the display panel, the support member possesses anisotropy in bending strength so as to encourage one-dimensional deformation (bending along only the X direction) of the display panel while suppressing two-dimensional deformation (bending in the X direction as well as the Y direction) of the display panel.
1. A display device comprising:
a plurality of pixels in matrix;
a substrate on which the plurality of pixels are formed; and
a support member under the substrate;
wherein the substrate is arranged on a front surface of the support member; wherein each of the substrate and the support member is formed in substantially rectangular shape and has a first side, a second side, a third side facing to the first side, and a fourth side facing to the second side;
wherein a dent is formed on a rear surface of the support member and covers a whole region of the rear surface; and
wherein a first width of a cross section of the dent gradually becomes thicker in a first direction extending from a first end portion of the substrate corresponding to the first side to a central portion of the substrate, and a second width of the cross section of the dent gradually becomes thicker in a second direction opposite to the first direction extending from a second end portion of the substrate corresponding to the third side to the central portion of the substrate.
2. The display device according to claim 1 , wherein bending strength of the support member in a third direction which is substantially perpendicular to the first and second directions is smaller than bending strength of the support member in the first and second directions.
3. The display device according to claim 2 , wherein the substrate is formed of plastic material.
