A display device includes a first substrate, at least one trace, a hydrophobic protective layer, a flexible printed circuit board (FPCB), a second substrate and a sealant. The first substrate has a display region and a peripheral region having an outer lead bonding (OLB) portion. The trace and the hydrophobic protective layer are disposed on the first substrate and extend from the display region to the OLB portion. The hydrophobic protective layer covers the trace and has at least one opening exposing a portion of the trace to define at least one lead and a surface microstructure. The lead and the surface microstructure are located in the OLB portion, and the surface microstructure is located on a surface of the hydrophobic protective layer away from the trace. One end of the FPCB leans against the surface microstructure and the FPCB is electrically connected to the lead.

摘要:
The invention relates to an optical film containing aromatic polymer which shows high solubility to solvents, and methods for production thereof. Further, the invention also relates to an optical laminate, a polarizing plate, and an image display device each using the optical film. The optical film may be attained by using polyester with a specific structure. The polyester with a specific structure may be obtained by condensation polymerization of bisphenol compound(s) and dicarboxylic acid compound(s) with biphenyl structure, and preferably has no halogen atom in its chemical structure. The optical film of the invention advantageously has not only high solubility in solvents but also a high level of heat resistance and birefringence producing capability. When the content of the biphenyl structure is high, the optical film of the invention can also have large wavelength dispersion of birefringence.
