Display module
A display module includes: a display panel including a substrate, a transistor layer disposed on the substrate and including transistors, and a display layer disposed on the transistor layer and including a display element, where the display panel defines a groove or a through-hole therein; a base film including a first portion disposed on the display panel so that a portion of the first portion overlaps the groove or the through-hole, and a second portion connected to the first portion, wherein the base film defines a first indentation portion between the first portion and the second portion; and an adhesive layer bonding the first portion to the display panel.
1 . A display module comprising:
a display panel comprising a substrate, a transistor layer disposed on the substrate and comprising transistors, and a display layer disposed on the transistor layer and comprising a display element, wherein the display panel defines a groove or a through-hole therein;
a base film comprising a first portion disposed on the display panel so that a portion of the first portion overlaps the groove or the through-hole, and a second portion connected to the first portion, wherein the base film defines a first indentation portion between the first portion and the second portion; and
an adhesive layer bonding the first portion to the display panel.
2 . The display module of claim 1 , further comprising a sensor inserted into the groove or the through-hole.
3 . The display module of claim 1 , wherein the base film further defines a second indentation portion between the first portion and the second portion, and the second indentation portion faces the first indentation portion.
4 . The display module of claim 3 , wherein, with respect to an imaginary line extending from a center of the first portion to a center of the second portion, the first indentation portion is located on one side of the imaginary line and the second indentation portion is located on an opposite side of the imaginary line.
5 . The display module of claim 4 , wherein a first edge of the first indentation portion in a direction to the first portion and a 1 St-1 St edge of the first portion connected to the first edge form a first preset angle.
6 . The display module of claim 5 , wherein the first preset angle is a right angle.
7 . The display module of claim 5 , wherein, when viewed from a direction perpendicular to the base film, the adhesive layer has a chamfered shape at a corner formed by the 1 st -1 st edge and the first edge.
8 . The display module of claim 5 , wherein, when viewed from a direction perpendicular to the base film, the adhesive layer has a round shape at a corner formed by the 1 st -1 st edge and the first edge.
9 . The display module of claim 5 , wherein a second edge of the second indentation portion in the direction to the first portion and a 1 st -2 nd edge of the first portion connected to the second edge form a second preset angle.
10 . The display module of claim 9 , wherein the second preset angle is equal to the first preset angle.
11 . The display module of claim 9 , wherein each of the first preset angle and the second preset angle is a right angle.
12 . The display module of claim 9 , wherein, when viewed from a direction perpendicular to the base film, the adhesive layer has a chamfered shape at each of a corner formed by the 1 st -1 st edge and the first edge and a corner formed by the 1 st -2 nd edge and the second edge.
13 . The display module of claim 9 , wherein, when viewed from a direction perpendicular to the base film, the adhesive layer has a round shape at each of a corner formed by the 1 st -1 st edge and the first edge and a corner formed by the 1 st -2 nd edge and the second edge.
14 . The display module of claim 5 , wherein a third edge of the first indentation portion in a direction to the second portion and a 2 nd -1 st edge of the second portion connected to the third edge form a third preset angle that is different from the first preset angle.
15 . The display module of claim 14 , wherein the first preset angle is a right angle and the third preset angle is an obtuse angle.
16 . The display module of claim 5 , wherein a third edge of the first indentation portion in a direction to the second portion and a 2 nd -1 st edge of the second portion connected to the third edge form a third preset angle that is different from the first preset angle, and a fourth edge of the second indentation portion in a direction to the second portion and a 2 nd -2 nd edge of the second portion connected to the fourth edge form the third preset angle.
17 . The display module of claim 1 , wherein the adhesive layer defines an opening therein corresponding to the groove or the through-hole.
18 . The display module of claim 1 , wherein the adhesive layer encircles the groove or the through-hole when viewed from a direction perpendicular to the base film.
19 . The display module of claim 1 , wherein the base film further defines an additional indentation portion located in the first portion.
20 . The display module of claim 1 , wherein the first portion is integral with the second portion.
