Abstract

The display panel of this invention includes a pair of glass substrates each with a thickness not less than 0.15 mm and not more than 0.3 mm and a sealing material for bonding the pair of glass substrates to each other. A resin layer is formed on the outer face of at least one of the pair of glass substrates.

Claims

1. A method for fabricating a display panel that includes a pair of glass substrates each with a thickness not less than 0.15 mm and not more than 0.3 mm and a sealing material for bonding the pair of glass substrates to each other and in which a resin layer is formed on both faces of the display panel, the method comprising:

forming a pair of layered plates each by placing a supporting substrate on each of the pair of glass substrates with the resin layer sandwiched therebetween;

aligning the pair of layered plates with the sealing material sandwiched therebetween and with the supporting substrates facing outside, and

removing the supporting substrates from the pair of aligned layered plates by chemical etching.

2. The method for fabricating a display panel of claim 1, wherein the supporting substrate has a thickness of 0.5 mm or more.

3. The method for fabricating a display panel of claim 2, wherein the resin layer has a thickness not less than 2 μ

m and not more than 50 μ

m.

4. The method for fabricating a display panel of claim 2, wherein the resin layer is a layer mainly made of an organic resin, or a layer including a hybrid material composed of inorganic colloid particles and an organic binder resin.

5. The method for fabricating a display panel of claim 1, wherein the resin layer has a thickness not less than 2 μ

m and not more than 50 μ

m.

6. The method for fabricating a display panel of claim 1, wherein the resin layer is a layer mainly made of an organic resin, or a layer including a hybrid material composed of inorganic colloid particles and an organic binder resin.
