For example, the second pixel region PXA-R and the third pixel region PXA-B can be arranged alternately along the first direction DR1, and the first pixel region PXA-G can be arranged alternately with the second pixel region PXA-R and the third pixel region PXA-B along the diagonal directions of the first direction DR1 and the second direction DR2, respectively.

[0106] According to one embodiment, the area of ​​the second pixel region PXA-R can be smaller than the area of ​​the first pixel region PXA-G, and can be larger than the area of ​​the third pixel region PXA-B.

[0107] In this embodiment, a first pixel region PXA-G, a second pixel region PXA-R, and a third pixel region PXA-B with square shapes are shown as an example, but the arrangement and area of ​​the pixel regions are not limited thereto.

[0108] Figure 4 The arrangement of the first pixel regions PXA-G, the second pixel regions PXA-R, and the third pixel regions PXA-B within the pixel unit PXU shown is merely an example and is not limited thereto. In one embodiment of this invention, the first pixel regions PXA-G, the second pixel regions PXA-R, and the third pixel regions PXA-B may also be arranged along the first direction DR1 and in the same row. Furthermore, the arrangement of the first pixel regions PXA-G, the second pixel regions PXA-R, and the third pixel regions PXA-B in each pixel unit PXU does not necessarily need to be identical.

[0109] Figure 5 This is a plan view of a plate according to an embodiment of the present invention. It will be... Figure 5The CH plate described in the text can be applied to... Figures 2a to 2b The CH plate is described in the text.

[0110] According to one embodiment, the board CH may include a first sheet IP and a plurality of second sheets SP disposed on the first sheet IP. The first sheet IP may be separated from the heat dissipation layer GS (see reference) through the second sheets SP. Figure 2a Separated by ) The CH board can be bonded to the heat dissipation layer GS via a separate adhesive layer AS.

[0111] The first sheet IP can be provided as a plate having a rectangular shape along the first direction DR1 and the second direction DR2. The first sheet IP can include a material that is softer than the second sheet SP. For example, the first sheet IP can include Invar. Since the plate CH according to one embodiment uses the first sheet IP, which is softer than the second sheet SP, to support the second sheet SP, the shape of the plate CH can be easily deformed.

[0112] According to one embodiment, the thickness of the first sheet IP can be more than 25 μm and less than 100 μm.

[0113] Each of the second sheet SPs can be spaced apart from each other along the first direction DR1 and the second direction DR2 and arranged on the first sheet IP. Each of the second sheet SPs can be bonded to the first sheet IP by welding or brazing.

[0114] Each of the second sheet SP may include a first hole H1, a second hole H2, and a third hole H3. In this embodiment, the first hole H1, the second hole H2, and the third hole H3 may extend along a first direction DR1, respectively.

[0115] The first hole H1 and the second hole H2 can be separated by a first direction DR1. The third hole H3 can be separated from the first hole H1 by a first oblique line direction of the first direction DR1 and the second direction DR2, and the third hole H3 can be separated from the second hole H2 by a second oblique line direction of the first direction DR1 and the second direction DR2. The first oblique line direction and the second oblique line direction can intersect each other.

[0116] The widths of the first hole H1 and the second hole H2 in the first direction DR1 can be greater than the width of the third hole H3 in the first direction DR1.

[0117] When viewed from the second direction DR2, a portion of the second hole H2 can overlap with the first hole H1, and another portion of the second hole H2 can overlap with the third hole H3.

[0119] In Figure 5 shows a case where 11 holes are defined in one second sheet SP, but the number of holes is not limited to this, as long as the hole combination and the second hole H2 are alternately arranged.

[0120] According to this embodiment, the second sheet SP may include a material having a strength greater than that of the first sheet IP. For example, the second sheet SP may include stainless steel. Since the second sheet SP includes stainless steel, the plate CH can maintain the flatness of the display panel DP.

[0121] The thickness of each second sheet SP may be 50 μm or more and 200 μm or less.

[0122] In this embodiment, a case where 20 second sheets SP are arranged on the first sheet IP in a 4×5 matrix form is shown, but the number of second sheets SP is not limited to this, and the number and width of the second sheets SP can vary according to the area of the display panel DP (refer to Figure 2a ).

[0123] According to this embodiment, since the plate CH includes the second sheet SP containing stainless steel, while maintaining the flatness of the plate CH, the second sheets SP can be arranged spaced apart from each other on the first sheet IP, and since the first sheet IP supporting the second sheets SP includes invar, the shape of the plate CH can be easily deformed. And, a lightweight and large-sized plate CH can be provided. Accordingly, a display device DD including a display panel DP with improved reliability can be provided. 0]

[0140] The first sheet IP can be provided as a plate having a rectangular shape along the first direction DR1 and the second direction DR2. The first sheet IP may include Invar. Since the plate CH-3 according to one embodiment uses the first sheet IP, which is more flexible than the second sheet SP, to support the second sheet SP, the shape of the plate CH-3 can be easily deformed.

[0141] According to one embodiment, the thickness of the first sheet IP can be more than 25 μm and less than 100 μm.

[0142] According to this embodiment, the second sheets SP1 arranged along the first direction DR1 in the second sheet SP can be in contact with each other.
