Abstract

A display device includes first and second transparent substrates; a plurality of gate bus lines and data bus lines on the first transparent substrate to define a plurality of pixels; a plurality of color filter layers under the second transparent substrates; and a plurality of microlenses under one of the first and second transparent substrates at positions corresponding to the gate and data bus lines, wherein at least two microlenses among the plurality of microlenses are corresponded to each of the gate or data bus lines in a width direction of each of the gate or data bus lines, and wherein a border between the at least two microlenses is substantially aligned with a center of a corresponding one of the gate and data bus lines, and wherein at least one microlens overlapped with one data bus line does not overlap with the other data bus lines.

Claims20

Dependent claims

A display device comprising:

a substrate;
a plurality of gate bus lines and a plurality of data bus lines intersecting the plurality of gate bus lines on the substrate;
a plurality of pixel regions arranged between the plurality of data bus lines and the plurality of gate bus lines on the substrate;
a plurality of pixel electrodes on the substrate at each of the plurality of pixel regions;
and
a plurality of microlenses over the substrate,
wherein at least three microlenses among the plurality of microlenses are corresponded to each of the pixel electrodes in a width direction of the each of the pixel electrodes, and at least one microlens adjacent to the at least three microlenses is corresponded to one of the plurality of data bus lines,
wherein at least two microlenses among the plurality of microlenses are corresponded to each of the gate or data bus lines in a width direction of each of the gate or data bus lines, and
wherein at least one microlens among the at least two microlenses that is overlapped with one data bus line does not overlap with the other data bus lines.
