In a wiring figure pattern of a display panel, each wiring is separated
into bands of optimal widths by slits of a constant width as a wiring
figure pattern so that minimum light irradiation for curing a photocuring
sealing material can be carried out without increasing the electric
resistance of the wiring. The optimal width means a resistance such that
light coming from both sides of the band cures the sealing material on
the upper surface of the band-without influencing the driving and display
of liquid crystal. At a point where the width of wiring becomes two times
or more of the optical width between the start point and end point of
intersection of the wiring and the sealing material region, the wiring is
divided by the slit. A first branch forms the band of the optimal width
extending from the branch point to the end point, whereas the second
branch extends to the end point and is spaced apart from the first branch
by the width of the slit. At a point where the width becomes two times or
more of the optimal width, the wiring is divided. Subsequently, branching
is repeated until the end point is reached. A continuous triangle is
formed in the slit at each branch, thus adjusting the width of the bands
to have the optimal width.
