Display device and manufacturing method therefor
View Patent ↗Disclosed herein is a display device including a pair of substrates opposed to each other, a pixel region provided between the substrates, and an external wiring provided on an extension of one of the substrates. The external wiring is disposed in a recess formed on the extension. With this structure, the external wiring provided on the extension can be reliably protected to thereby improve the reliability of the display device.
1. A display device comprising a pair of substrates opposed to each other, a pixel region provided between said substrates, and an external wiring provided on an extension of one of said substrates;
said external wiring being disposed in a recess formed on said extension.
2. A display device according to claim 1 , wherein the depth of said recess is greater than or equal to the height of said external wiring.
3. A display device according to claim 1 , further comprising a multilayer thin film formed on said extension in the periphery of said recess;
the depth of said recess extending from said multilayer thin film to said substrate having said extension.
4. A display device according to claim 1 , further comprising a circuit element provided on said extension, and an external wiring member connected to said extension;
said recess being formed between said circuit element and a connected portion of said external wiring member.
5. A manufacturing method for a display device having a pair of substrates opposed to each other, a pixel region formed between said substrates, and an external wiring formed on an extension of one of said substrates for inputting a signal to said pixel region, said manufacturing method comprising the steps of:
forming a recess on said extension; and
disposing said external wiring in said recess.
6. A manufacturing method according to claim 5 , further comprising the step of forming through holes in the formation of said pixel region;
said step of forming said recess being the same as said step of forming said through holes.
7. A manufacturing method according to claim 5 , wherein the depth of said recess is greater than or equal to the height of said external wiring.
8. A manufacturing method according to claim 5 , wherein said display device further has a multilayer thin film formed on said extension in the periphery of said recess;
the depth of said recess extending from said multilayer thin film to said substrate having said extension.
