The liquid crystal display includes a first substrate, a second substrate facing the first substrate and a liquid crystal layer interposed between the first and second substrates. The first substrate includes a first base substrate, a bump protruded from the first base substrate and an electrode having a shield electrode part and a common electrode part. The shield electrode part covers the bump. The second substrate includes a second base substrate and a spacer protruded toward the bump of the first substrate. A combined structure of the spacer and the bump supports the first and second substrates. ## Claims ### Claim 1 A liquid crystal display comprising: a first substrate; a second substrate facing the first substrate; and a liquid crystal layer interposed between the first and second substrates, wherein the first substrate comprises: a first base substrate; a first electrode disposed on the first base substrate; a second electrode including a shield electrode part and a common electrode part, wherein the second electrode is insulated from the first electrode and overlapped with the first electrode; a gate line disposed on the first base substrate; a data line crossing the gate line; a first bump which is protruded from the first base substrate extends along the data line and is disposed on the data line; wherein the first bump comprises a first part which is covered by the shield electrode and a second part which is not covered by the shield electrode, and wherein the second substrate comprises: a second base substrate; a color filter layer including a plurality of color pixels disposed on the second base substrate; and a spacer overlapping a portion where the gate line and the data line cross each other, the spacer protruded toward the first substrate, wherein the spacer comprises a same material as at least one of the plurality of color pixels, and wherein a combined structure of the spacer and the second part of the first bump is configured to support the first and second substrates. ### Claim 2 (depends on 1) The liquid crystal display of claim 1, wherein the spacer has a height greater than a height of each of the plurality of color pixels. ### Claim 3 (depends on 2) The liquid crystal display of claim 2, wherein the first substrate is in contact with the second substrate in an area where the spacer and the first bump are overlapped. ### Claim 4 (depends on 1) The liquid crystal display of claim 1, wherein the first substrate is in contact with the second substrate in a first area where the main spacer is disposed, and wherein the first substrate is spaced apart from the second substrate in a second area where the sub-spacer is disposed. ### Claim 5 (depends on 1) The liquid crystal display of claim 1, wherein the first substrate further comprises: a thin film transistor connected to the gate line and the data line to apply a driving voltage to the first electrode, and wherein the second substrate further comprises: a black matrix disposed on the second base substrate, wherein the black matrix is disposed on the gate line, the data line, and the thin film transistor. ### Claim 6 (depends on 5) The liquid crystal display of claim 5, wherein the spacer is disposed on the black matrix. ### Claim 7 (depends on 1) The liquid crystal display of claim 1, wherein the plurality of color pixels comprises at least one of a red color pixel, a green color pixel, and a blue color pixel. ### Claim 8 (depends on 7) The liquid crystal display of claim 7, wherein the spacer comprises a same material as the red color pixel. ### Claim 9 (depends on 1) The liquid crystal display of claim 1, wherein the spacer has an oval shape or a circular shape. ### Claim 10 (depends on 1) The liquid crystal display of claim 1, wherein the common electrode part is disposed at a center of the first electrode, and the shield electrode part of the second electrode is partially overlapped with the first electrode. ### Claim 11 (depends on 1) The liquid crystal display of claim 1, wherein the common electrode part of the second electrode is substantially in parallel to the data line. ### Claim 12 (depends on 2) The liquid crystal display of claim 2, wherein the spacer comprises a main spacer having a first height and a sub-spacer having a second height smaller than the first height. ### Claim 13 (depends on 12) The liquid crystal display of claim 12, wherein the first substrate further comprises: a second bump protruded from the first base substrate, wherein the second substrate further comprises: an overcoating layer including a first portion interposed between the main spacer and the first bump of the first substrate and a second portion interposed between the sub-spacer and the second bump of the first substrate, wherein the sub-spacer protrudes toward the second bump, wherein the first portion of the overcoating layer is in direct contact with the first bump, and wherein the second portion of the overcoating layer is spaced apart from the second bump.
