Flexible display panel and electro-optical apparatus

Abstract

A first etching stop layer and an active layer are formed on an inner surface of a first glass substrate, and a second etching stop layer and a cover layer are formed on an inner surface of a second glass substrate. A display media is formed between the first glass substrate and the second glass substrate. A first passivation layer is formed on an outer surface of the second glass substrate. A first etching process is performed to expose the first etching stop layer. A first flexible substrate is formed on the exposed first etching stop layer, and a second passivation layer is formed on the first flexible substrate. The first passivation layer is removed. A second etching process is performed to expose the second etching stop layer. A second flexible substrate is formed on the exposed second etching stop layer, and the second passivation layer is removed.

1 . A flexible display panel, comprising:
 a first flexible substrate, having a first etching stop layer and an active layer disposed thereon, wherein the material of the first etching stop layer comprises polyamide or silicon-rich dielectric material;   a second flexible substrate, having a second etching stop layer and a cover layer disposed thereon, wherein the material of the second etching stop layer comprises polyamide or silicon-rich dielectric material; and   a display media, disposed between the first flexible substrate and the second flexible substrate.   
     
     
         2 . The flexible display panel of  claim 1 , wherein at least one of the first flexible substrate and the second flexible substrate comprise plastic substrates, metal substrates, glass having curvatures, or combinations of at least two of the above substrates. 
     
     
         3 . The flexible display panel of  claim 1 , wherein at least one of the first flexible substrate and the second flexible substrate have functions of polarization, phase difference, brightness enhancement, light delay, or at least two of the above functions. 
     
     
         4 . The flexible display panel of  claim 1 , wherein an adhesive layer is disposed at least one of between the first etching stop layer and the active layer and between the second etching stop layer and the cover layer. 
     
     
         5 . An electro-optical device, comprising a flexible display panel of  claim 1 .
