摘要

A display apparatus includes display panel configured to display an image from one side of the display panel; a first member disposed at another side of the display panel; a first adhesive layer disposed at an upper portion of the first member; a second member disposed at an upper portion of the first adhesive layer; and a first heat-dissipation layer disposed at an upper portion of the second member, wherein the second member includes a first area including a central area of the second member, and a second area including at least three outer edges of the second member, wherein the second member has a vertical dimension or a shape in the first area different from a vertical dimension or a shape of the second member in the second area.

說明書

With reference to FIG. 8, the thickness of the second member 36 may have a value of T1 in the first area and may have a value of T2 in the second area C in which the valley or the groove of the unevenness pattern is formed. The value of T1 may be greater than the value of T2. The depth or the vertical dimension of the valley or the groove of the unevenness pattern in the second area C may be equal to a d1 value as a difference between the T1 value and the T2 value.

The first heat-dissipation layer 35 and the second member 36 are sequentially cut along the cutting line CL via the laser beam irradiation. Since the second member 36 has rigidity greater than that of the first heat-dissipation layer 35, cutting of the second member 36 via the laser beam irradiation requires greater thermal energy than that which cutting of the first heat-dissipation layer 35 requires. Due to the greater thermal energy required for cutting the second member 36, thermal deformation of or thermal damage to the structure above and/or below the second member 36 may occur.
