Prospects

Display is one of the major technologies of Korean

industry and is expected to expand continuously, at least, for

the time being.

Korean companies lead the display technology these days.

Various mobile devices for ubiquitous communications and

large-size, ultra high resolution displays will be a mainstream

in this field.

Flexible, transparent displays will enter the market soon.

Job opportunity in this field has been and will remain high.
