Abstract

Disclosed are the multi-domain vertical aligned nematic (VAN)-mode liquid crystal display (LCD) structures that are composed of the ridges which are combined with Color-filter-on-array (CFA) structure or spacer-ball-free (SBF) structure without any additional process.

Liquid Crystal Display

   Disclosed are the multi-domain vertical aligned
nematic (VAN)-mode liquid crystal display (LCD) structures that are
composed of the ridges which are combined with Color-filter-on-array
(CFA) structure or spacer-ball-free (SBF) structure without any
additional process.

   The figure 1 shows an example of this device combined
with CFA structure.  Color filter layers, which are three layers
(1),(2),(3), are on the one side.  In this case, (1),(2),(3) are
red(R), green(G), and blue(B), respectively.  These color filter
layers makes ridge (4) and ridge (5) when these layers are piled up,
which are shown in figure 1.  Transparent electrode (6) is covering
the ridge (4), but it is not covering the ridge (5).  Counter
electrode (7) is mounted on the other side.  Using these structures,
VAN-mode liquid crystal (8) is divided at the point of ridge (4) and
(5) shown as figure 1, as a result, multi-domain VAN-mode LCD is
realized.

   The figure 2 shows an example of this device combined with
SBF structure.  Color filter layers, which are three layers (9),
(10), (11) are on the one side.  Color filter layers are piled up
(12) to make the stack at a part of the pixel.  On the color filter
layers, transparent electrode (13) is mounted.  After that, on the
stack (12), the resin (14) is piled up.  This stack makes the cell
gap.  At the same time, the resin (15) is piled up in the middle of
the pixel to make the ridge.  Counter electrode (16) is mo...
