The display module assembly WS may include a display module DM and a housing member FS. The display module DM may display an image through an electrical signal. The display module DM may include a display panel DP and a driving circuit DB.

For example, the display panel DP may be an organic light emitting display panel, a liquid crystal display panel, a plasma display panel, an electrophoretic display panel, or an electrowetting display panel.

The display panel DP may include a front surface PS, a rear surface PB, and a plurality of side surfaces S1, S2, S3, and S4. In the present embodiment, the front surface PS, the rear surface PB, and the side surfaces S1, S2, S3, and S4 may be connected to each other to realize the display panel DP having a hexahedral shape. However, embodiments of the inventive concept are not limited thereto. In other embodiments, various modifications may be made to the shape of the display panel DP.

The display panel DP may display an image on the front surface PS. The front surface PS may include a display area DA and a peripheral area NDA. An image may be displayed in the display area DA. The peripheral area NDA may be adjacent to the display area DA. The peripheral region NDA may define an area (or size) and a shape of the display region DA. However, embodiments of the inventive concept are not limited thereto. In another embodiment, the peripheral region NDA may be omitted in the display panel DP.

The side surfaces S1, S2, S3, and S4 may be parallel to the third direction DR3 and may be connected to each other. The third direction DR3 may be the same as a direction defining the thickness of the display panel DP.

The first side surface S1 may extend in the first direction DR 1. The second side surface S2 may extend in the first direction DR1 and may be spaced apart from the first side surface S1 in the second direction DR 2. The third side surface S3 may extend in the second direction DR 2. The fourth side surface S4 may extend along the second direction DR2 and may be spaced apart from the third side surface S3 in the first direction DR 1. The third side surface S3 may connect one end of the first side surface S1 and one end of the second side surface S2, and the fourth side surface S4 may connect the other end of the first side surface S1 and the other end of the second side surface S2.

The driving circuit DB may be disposed at one side of the display panel DP. Even though not shown in the drawings, the pad of the driving circuit DB may be connected to a corresponding pad of the display panel DP. The connection between the driving circuit DB and the display panel DP may include physical and electrical connections between the pads. In the present embodiment, the driving circuit DB may be connected to the front surface PS (or the top surface) of the display panel DP. However, embodiments of the inventive concept are not limited thereto. In other embodiments, the driving circuit DB may be connected to one of the side surfaces S1, S2, S3, and S4 of the display panel DP, and may be accommodated in the accommodating member FS.

The driving circuit DB may include a circuit film CF, a driving chip DIC, and a circuit board MB. A plurality of driving circuits DB may be provided, and the plurality of driving circuits DB may be arranged in the first direction DR 1. However, embodiments of the inventive concept are not limited thereto. In other embodiments, the driving circuit DB may be provided as a single component including one circuit film, one driving chip, and one circuit board.

The circuit film CF may have flexibility and may include a plurality of circuit interconnection lines (not shown). The circuit film CF may be disposed on one side of the front surface PS of the display panel DP. The shape of the circuit film CF may be variously modified to correspond to the shape of the driving circuit DB.

The driving chip DIC may include a plurality of electronic elements. The driving chip DIC may be electrically connected to the circuit board MB and the display panel DP. The driving chip DIC may generate an electrical signal and/or process the received electrical signal, and may provide the generated electrical signal and/or the processed electrical signal to the circuit board MB and/or the display panel DP. The driving chip DIC may be mounted on the circuit film CF in the form of a Chip On Film (COF). Accordingly, the driving chip DIC may be electrically connected to the display panel DP through the circuit film CF. However, embodiments of the inventive concept are not limited thereto. In other embodiments, the driving chip DIC may be directly mounted on the display panel DP.

The circuit board MB may be electrically connected to the circuit film CF. The circuit board MB may comprise a plurality of electronic components for generating and/or processing electrical signals. The circuit board MB can exchange electrical signals with the display panel DP through the circuit film CF. The circuit board MB may include a Flexible Printed Circuit Board (FPCB).

The receiving member FS may include connection portions F1, F2, F3, and F4 and a seating portion CM. The receiving member FS may provide a receiving space (or an inner space) defined by the connection portions F1, F2, F3, and F4 and the seating portion CM. The receiving space may have a size capable of receiving the display module DM. The shape of the receiving space may be variously modified according to the shape of the display module DM. However, the inventive concept is not limited to a specific embodiment.

The connection portions F1, F2, F3, and F4 may include a first connection portion F1, a second connection portion F2, a third connection portion F3, and a fourth connection portion F4. The first and second connection portions F1 and F2 may extend in the first direction DR1 and may be spaced apart from each other in the second direction DR 2. The third and fourth connection portions F3 and F4 may be spaced apart from each other in the first direction DR1 and may extend in the second direction DR2 to connect the first and second connection portions F1 and F2. Each of the connection portions F1, F2, F3, and F4 may include an inner side surface facing the seat portion CM, an outer side surface opposite to the inner side surface, and a top surface connecting the inner side surface and the outer side surface. For example, the first connection portion F1 may include a first inner side surface F1A, a first outer side surface F1B, and a first top surface F1C, and the second connection portion F2 may include a second inner side surface F2A, a second outer side surface F2B, and a second top surface F2C.

The seating portion CM may support the display module DM in the receiving space (or the inner space). The seating portion CM may be surrounded by the connection portions F1, F2, F3, and F4. The display module DM may be received on a seat portion CM defining a part of the receiving space. The seating portion CM may include an inclined portion GM and a receiving portion SM.

The inclined portion GM may support the display panel DP of the display module DM. The inclined portion GM may be an area on which the rear surface PB of the display panel DP is directly disposed. As shown in fig. 1B, the inclined portion GM may overlap the display panel DP in a plan view. The inclined portion GM may include a top surface including an inclined surface G1 and a vertical surface G2. According to an embodiment of the inventive concept, the area of the inclined surface G1 may be equal to or greater than the area of the display panel DP.

The inclined surface G1 may form a predetermined angle with the second inner side surface F2A of the second connection portion F2. The inclined surface G1 according to an embodiment of the inventive concept may have a height variation in which the height gradually becomes higher from the second connection portion F2 toward the first connection portion F1.

The vertical surface G2 may be connected to one side of the inclined surface G1. The vertical surface G2 may extend from one side of the inclined surface G1 in parallel to the third direction DR3 and may be connected to the accommodating portion SM. In an embodiment, the vertical surface G2 may be parallel to the first inner side surface F1A.

The accommodating part SM may be connected to the inclined part GM through the vertical surface G2. The accommodating portion SM may overlap with the driving circuit DB of the display module DM when viewed in a plan view. The receiving portion SM may have a top surface M1 recessed from one side of the inclined surface G1. The first inner side surface F1A, the top surface M1, and the vertical surface G2 may define a predetermined space recessed from the inclined surface G1. The driving circuit DB of the display module DM may be accommodated in a space recessed from the inclined surface G1.

As shown in fig. 2B, the inclined surface G1 may be inclined at a first angle θ 1 from a plane parallel to the top surface M1. The first angle θ 1 may be an acute angle.

Meanwhile, the inclined surface G1 may be inclined at a second angle θ 2 from the second inner side surface F2A of the second connection portion F2. The second angle θ 2 may be an acute angle. The top surface M1 and the first inner side surface F1A of the first connection portion F1 may form a third angle θ 3 therebetween. The sum of the first angle θ 1 and the second angle θ 2 (i.e., the sum of the inner angle and the outer angle) may be 90 degrees.

The third angle θ 3 may be 90 degrees. In an embodiment, each of the first angle θ 1 and the second angle θ 2 may be less than the third angle θ 3.

The display module DM may be accommodated in the accommodating member FS, transferred or held while being accommodated in the accommodating member FS. Due to the partitioned space between the display module DM and the receiving member FS, slippage of the display module DM may occur during the process of receiving, transferring, or holding the display module DM. In the present embodiment, the first slip K1 and the second slip K2 corresponding to the movements in the opposite directions with respect to each other are shown as an example of the slip of the display module DM. The first slip K1 may refer to the movement of the display module DM in an uphill direction (e.g., a diagonal direction between the third direction DR3 and a direction opposite to the second direction DR 2) along the inclined surface G1. The second slip K2 may refer to the movement of the display module DM in a downhill direction (e.g., a diagonal direction between the second direction DR2 and a direction opposite to the third direction DR 3) along the inclined surface G1 (i.e., in a direction opposite to the first slip K1).

Fig. 3A illustrates a case where a first slip K1 of the display module DM occurs in the receiving member FS, and thus a separation distance TH occurs between the display module DM and the receiving member FS. According to an embodiment of the inventive concept, the seating portion CM on which the display module DM is directly disposed may include an inclined portion GM having a predetermined inclination. Therefore, even if the first slip K1 occurs during the process of accommodating, conveying, or holding the display module DM, the load of the display module DM may be concentrated downward along the inclined surface G1, and thus the display module DM moved due to the first slip K1 may be easily returned to its original position (see fig. 3B). In other words, the second shuffle K2 of the display module DM may easily occur as shown in fig. 3B. According to an embodiment of the inventive concept, the display module assembly WS in which the display module DM is stably received in the receiving member FS may be provided by the receiving member FS capable of easily moving (second sliding K2) the display module DM, which has undergone the first sliding K1, to its original position.

Fig. 4 is a sectional view illustrating a display module assembly according to an embodiment of the inventive concept. Hereinafter, the same components as those described with reference to fig. 1A to 3B will be denoted by the same reference numerals, and the description thereof will be omitted for the convenience and convenience of description.

According to an embodiment of the inventive concept, the circuit film CF-Sub>A may be bent in the receiving member FS. The display panel DP-ase:Sub>A of the display module DM-ase:Sub>A may be disposed directly on the inclined portion GM, and the driving circuit DB-ase:Sub>A of the display module DM-ase:Sub>A may be disposed in ase:Sub>A space surrounded by the first inner side surface F1 ase:Sub>A, the top surface M1, and the vertical surface G2 when viewed in ase:Sub>A sectional view. According to an embodiment of the inventive concept, the driving circuit DB-ase:Sub>A may include ase:Sub>A circuit film CF-ase:Sub>A, ase:Sub>A driving chip DIC-ase:Sub>A, and ase:Sub>A circuit board MB-ase:Sub>A. The driving circuit DB-ase:Sub>A may be spaced apart from the first inner side surface F1 ase:Sub>A, the top surface M1, and the vertical surface G2. Therefore, the circuit film CF-Sub>A may be bent toward the top surface M1. Even though not shown in the drawings, the circuit film CF-Sub>A may be bent, and thus the driving circuit DB-Sub>A may be in contact with the vertical surface G2.

As ase:Sub>A result, the circuit board MB-A of the driving circuit DB-A can be disposed in ase:Sub>A space and thus can be stably accommodated without interfering with other components.

Fig. 5A is a plan view illustrating a display module assembly according to an embodiment of the inventive concept. Fig. 5B is a partial sectional view of the display module assembly shown in fig. 5A. Hereinafter, the same components as described with reference to fig. 1A to 4 will be denoted by the same reference numerals, and the description thereof will be omitted for the simplicity and convenience of description.

As shown in fig. 5A, the display module assembly WS-1 may further include a plurality of support members QQ and PP. The support members QQ and PP may include a material having elasticity. According to an embodiment of the inventive concept, the supporting members QQ and PP may be adhered to at least one of the second to fourth connection portions F2-1 to F4-1.

The first support member QQ may support the third side surface S3 and the fourth side surface S4. The first support member QQ may be disposed between the third side surface S3 and an inner side surface of the third connecting portion F3-1 facing the third side surface S3 and/or between the fourth side surface S4 and an inner side surface of the fourth connecting portion F4-1 facing the fourth side surface S4. Fig. 5A shows a pair of first support members QQ supporting the third and fourth side surfaces S3 and S4. The first support member QQ may be disposed to face each other in the first direction DR1, and may support the third and fourth side surfaces S3 and S4 opposite to each other.

The second support member PP may support the second side surface S2. The second support member PP may be disposed between the second side surface S2 and a second inner side surface F2A-1 of the second connection portion F2-1 facing the second side surface S2. Fig. 5A illustrates a pair of second support members PP supporting the second side surface S2.

Fig. 5B illustrates a cross-sectional view of one second support member PP provided between the second inner side surface F2A-1 and the second side surface S2 to support the display panel DP. Since the support members QQ and PP according to the present inventive concept have elasticity, when the display panel DP applies pressure to the second support member PP by its load, the shape of the second support member PP may be deformed corresponding to the shape of the display panel DP. As shown in FIG. 5B, the second connection part F2-1 may include a second inner side surface F2A-1, a second outer side surface F2B-1, and a second top surface F2C-1.

The display module assembly WS-1 according to the present embodiment may include the supporting members QQ and PP disposed between the inner side surfaces of the other connecting portions except the inner side surface of the first connecting portion F1-1 and the side surfaces of the display panel DP except the first side surface S1, and thus, an impact applied when the sliding motions K1 and K2 (see fig. 3A and 3B) of the display module DM occur may be mitigated to stably protect the display module DM.

The supporting members QQ and PP according to the present embodiment may be spaced apart from the inner side surface of the first connection portion F1-1. Therefore, the supporting members QQ and PP do not overlap the first side surface S1 and the inner side surface of the first connection portion F1-1. According to an embodiment of the inventive concept, when the first slip K1 (see fig. 3A) of the display module DM occurs in the receiving member FS, the display module DM may be returned to its original position (the second slip K2, see fig. 3B) by the inclined portion GM-1. Accordingly, the collision between the first side surface S1 of the display panel DP and the first connection portion F1-1 may be prevented. As a result, an additional supporting member between the first connection portion F1-1 and the first side surface S1 may be omitted, and thus collision/interference between the supporting member and the driving circuit may be prevented.

In fig. 5A, one or two support members QQ or PP may be provided on each inner side surface. However, embodiments of the inventive concept are not limited thereto. In other embodiments, two or more supporting members QQ may be provided on each inner side surface of the third and fourth connection parts F3-1 and F4-1, and/or one supporting member PP or three or more supporting members PP may be provided on the inner side surface of the second connection part F2-1.

Fig. 6A is a cross-sectional view illustrating a display module assembly according to an embodiment of the inventive concept. Fig. 6B is an enlarged view of the area 'AA' of fig. 6A. Fig. 6C is a cross-sectional view illustrating some components of a display module assembly according to an embodiment of the inventive concept. Hereinafter, the same components as those described with reference to fig. 1A to 5B will be denoted by the same reference numerals, and the description thereof will be omitted for the convenience and convenience of description.

Referring to fig. 6A and 6B, the inclined surface G1 may form a fourth angle θ 4 with the second inner side surface F2A-2 of the second connection portion F2-2. The fourth angle θ 4 may be a right angle. Referring to fig. 6A and 6B, the first connection portion F1-2 may include a first inner side surface F1A-2, a first outer side surface F1B-2, and a first top surface F1C-2, the second connection portion F2-2 may include a second inner side surface F2A-2, a second outer side surface F2B-2, and a second top surface F2C-2, and the seat portion CM-2 may include an inclined portion GM-2 and a receiving portion SM-2.

According to an embodiment of the inventive concept, the second inner side surface F2A-2 may not be parallel to the second outer side surface F2B-2 of the second connection portion F2-2. Therefore, even if the inclined portion GM-2 of the seating portion CM-2 includes the inclined surface G1, the fourth angle θ 4 may be 90 degrees by changing the shape of the second inner side surface F2A-2 of the second connection portion F2-2. According to an embodiment of the inventive concept, one side of the display panel DP having a hexahedral shape may be in close contact with the inclined surface G1 and the second inner side surface F2A-2 forming the fourth angle θ 4. Accordingly, the display module assembly WS-2 stably receiving the display module DM can be provided.

According to an embodiment of the inventive concept, when the second side surface S2 and the rear surface PB of the display panel DP are perpendicular to each other, the fourth angle θ 4 may be a right angle. Accordingly, the second inner side surface F2A-2 may be parallel to the second side surface S2. However, embodiments of the inventive concept are not limited thereto. In other embodiments, the fourth angle θ 4 between the second inner side surface F2A-2 and the inclined surface G1 may be changed corresponding to an angle between the second side surface S2 and the back surface PB of the display panel DP.

As shown in fig. 6C, the display module assembly WS-2 may further include a support member PP-1 disposed on the second inner side surface F2A-2. The support member PP-1 of fig. 6C may correspond to the second support member PP of fig. 5B.

The support member PP-1 according to the present embodiment may be disposed on the second inner side surface F2A-2. Since the second inner side surface F2A-2 forms the fourth angle θ 4 with the inclined surface G1, the second side surface S2 may be parallel to one surface of the support member PP-1 contacting the second side surface S2.

According to an embodiment of the inventive concept, an impact applied to the second side surface S2 of the display panel DP when the slip occurs may be mitigated by the support member PP-1. In addition, the contact area between the second side surface S2 and the support member PP-1 may be uniformly distributed, and thus the load of the display module DM may be prevented from being concentrated on one point. As a result, the reliability of the display module assembly WS-2 can be improved.

Fig. 7 is a plan view illustrating a display module assembly according to an embodiment of the inventive concept. Hereinafter, the same components as described with reference to fig. 1A to 6C will be denoted by the same reference numerals, and the description thereof will be omitted for the convenience and convenience of description.

The display module assembly WS-3 according to an embodiment of the inventive concept may further include an absorbent member PW. The absorbent member PW may comprise a material that reacts with water to form a metal hydroxide. For example, the moisture absorbing member PW may include a metal and/or a metal oxide, such as calcium (Ca), barium (Ba), calcium oxide (CaO), barium oxide (BaO), aluminum oxide (AlO), and/or magnesium oxide (MgO). In certain embodiments, the absorbent member PW may include organic and/or inorganic materials.

The connection portions F1-3, F2-3, F3-3 and F4-3 may include a concave portion HM receiving the absorbent member PW. The concave portion HM may be a space capable of accommodating the absorbent member PW, and the shape of the concave portion HM is not limited to a specific shape. In fig. 7, the absorbent member PW is shown in shadow, and the absorbent member PW is omitted in one of the concave portions HM.

In the present embodiment, a plurality of absorbent members PW are provided in each of the connecting portions F1-3, F2-3, F3-3 and F4-3. In other embodiments, the absorbent member PW may be provided in at least one of the connection portions F1-3, F2-3, F3-3, and F4-3, one absorbent member PW may be provided in each of the connection portions F1-3, F2-3, F3-3, and F4-3, or a single absorbent member PW having a ring shape may be provided in the connection portions F1-3, F2-3, F3-3, and F4-3 in a plan view.

According to the present embodiment, the moisture absorbing member PW may be disposed in the concave portion HM to block oxygen and moisture supplied from the outside from entering into the display module DM. As a result, the reliability of the display module assembly WS-3 can be improved during the accommodation, transfer or holding process.

Fig. 8A is a perspective view illustrating a display module assembly according to an embodiment of the inventive concept. Fig. 8B is a cross-sectional view of the display module assembly shown in fig. 8A. Hereinafter, the same components as described with reference to fig. 1A to 7 will be denoted by the same reference numerals, and the description thereof will be omitted for the simplicity and convenience of description.

As shown in fig. 8A and 8B, the display module assembly WS-4 may accommodate a plurality of stacked display modules. Fig. 8A shows the display module DM1 directly accommodated on the seating portion CM-4 and an additional display module DM2 stacked on the display module DM 1. The display module DM1 and the additional display module DM2 received in the receiving member FS-4 may overlap the seat portion CM-4 when viewed in a plan view. Each of the circuit film CF1 of the display module DM1 and the circuit film CF2 of the display module DM2 in the present embodiment may correspond to the circuit film CF-Sub>A shown in fig. 4. The circuit films CF1 and CF2 may be bent toward the top surface M1 of the receiving portion SM-4 and may be stacked. As shown in fig. 8A and 8B, the first connection portion F1-4 may include a first inner side surface F1A-4, a first outer side surface F1B-4, and a first top surface F1C-4, the second connection portion F2-4 may include a second inner side surface F2A-4, a second outer side surface F2B-4, and a second top surface F2C-4, the display module DM1 may include a display panel DP1 and a driving circuit DB1, the driving circuit DB1 may include a circuit film CF1, a driving chip DIC1, and a circuit board MB1, the additional display module DM2 may include a display panel DP2 and a driving circuit DB2, and the driving circuit DB2 may include a circuit film CF2, a driving chip DIC2, and a circuit board MB2.

According to the present embodiment, a plurality of display modules DM1 and DM2 may be stacked in one receiving member FS-4, and thus costs for receiving, transferring, or maintaining the display modules DM1 and DM2 may be reduced.

Since the display modules DM1 and DM2 are stacked on the inclined portion GM-4, the additional display module DM2 disposed at the upper position may include a part having the maximum height (or level) in the third direction DR 3. In fig. 8B, the driving chip DIC2 of the component of the additional display module DM2 has the highest height (or level) in the third direction DR 3. According to an embodiment of the inventive concept, the top surface of the driving chip DIC2 of the additional display module DM2 may have a height lower than the imaginary extension line YS connecting the top surface F1C-4 of the first connection portion F1-4 and the top surface F2C-4 of the second connection portion F2-4. Even though not shown in the drawings, when an additional display module assembly (not shown) is stacked on the display module assembly WS-4, the height of the top surface of the connection part may be higher than the maximum height of the display module DM2 disposed at the uppermost position, and thus the display modules DM1 and DM2 may be stably received in the receiving member FS-4 without colliding with the additional display module assembly (not shown). In the present embodiment, the driving chip DIC2 has the highest height (or level). However, embodiments of the inventive concept are not limited thereto. The member having the highest height may vary according to the shape of the display module, and the display modules may be stacked in such a manner that the member having the highest height is lower than the imaginary extension line YS. According to an embodiment of the inventive concept, the maximum height of the additional display module DM2 from the top surface M1 of the receiving portion SM-4 may be lower than the height from the top surface M1 of the receiving portion SM-4 to the top surface of each connection portion.

In the present embodiment, two display modules DM1 and DM2 are stacked. However, embodiments of the inventive concept are not limited thereto. In other embodiments, three or more display modules may be accommodated in the accommodating member by adjusting the heights of the connection portions F1-4, F2-4, F3-4, and F4-4.

Fig. 9B is a cross-sectional view of the display module assembly shown in fig. 9A. Fig. 9C is a cross-sectional view illustrating some components of a display module assembly according to an embodiment of the inventive concept. Fig. 9D is a cross-sectional view illustrating some components of a display module assembly according to an embodiment of the inventive concept. Hereinafter, the same components as described with reference to fig. 1A to 8B will be denoted by the same reference numerals, and the description thereof will be omitted for the convenience and convenience of description.

According to an embodiment of the inventive concept, the display module assembly WS-5 may further include a protection member MM. The protective member MM may be disposed between the stacked display modules. The protective member MM may be disposed between the stacked display modules to absorb an impact occurring when the display modules are received, transferred, or held. The protection member MM may include a material having elasticity. Fig. 9A illustrates the stacked display modules DM1-1 and DM2-1 corresponding to the display modules DM1 and DM2 of fig. 8A, and the protective member MM is disposed between the display module DM1-1 and the additional display module DM 2-1. As shown in fig. 9A and 9B, the receiving member FS-5 may include a first connection portion F1-5, a second connection portion F2-5, a third connection portion F3-5 and a fourth connection portion F4-5, and a seating portion CM-5, the first connection portion F1-5 may include a first inner side surface F1A-5, a first outer side surface F1B-5 and a first top surface F1C-5, and the second connection portion F2-5 may include a second inner side surface F2A-5, a second outer side surface F2B-5 and a second top surface F2C-5.

Fig. 9B shows a cross-sectional view of the display modules DM1-1 and DM2-1 stacked on the seating portion CM-5. The driving circuit DB1-1 of the display module DM1-1 and the driving circuit DB2-1 of the display module DM2-1 of fig. 9B may correspond to the driving circuit DB1 of the display module DM1 and the driving circuit DB2 of the display module DM2 of fig. 8B, respectively. As shown in FIG. 9B, the driving circuit DB1-1 may include a circuit film CF1-1, a driving chip DIC1-1 and a circuit board MB1-1, and the driving circuit DB2-1 may include a circuit film CF2-1, a driving chip DIC2-1 and a circuit board MB2-1.

According to an embodiment of the inventive concept, the flexible circuit film CF1-1 of the display module DM1-1, which is in direct contact with the inclined portion GM-5, may be bent toward the top surface M1 of the receiving portion SM-5.

The protective member MM according to the present embodiment may be disposed on the display module DM 1-1. A portion of the protection member MM overlapping with the bent portion of the circuit film CF1-1 in a plan view may be bent toward the top surface M1 due to elasticity of the protection member MM. In an embodiment, the protection member MM may be harder than the circuit film CF 1-1. Therefore, the bent portion of the protection member MM may be less bent than the circuit film CF1-1 bent toward the top surface M1.

An additional display module DM2-1 may be disposed on the protective member MM. The circuit film CF2-1 of the additional display module DM2-1 may be bent toward the top surface M1. At this time, the bent portion of the protection member MM may support the circuit board MB2-1 coupled to the circuit film CF 2-1.

Although not shown in the drawings, in another embodiment, the protective member MM may be directly disposed on the inclined surface G1 of the inclined portion GM-5. In addition, when a plurality of display modules are provided, the protective members MM may be disposed between the stacked display modules, respectively.

A protective member MM, which is harder than the circuit film CF1-1 of the display module DM1-1, may be disposed between the display modules DM1-1 and DM2-1 to support the display module DM2-1, and thus physical contact between the display modules DM1-1 and DM2-1 may be prevented. As a result, the reliability of the display module assembly WS-5 can be improved. In addition, the protective member MM may support the flexible circuit film CF2-1, and thus may prevent cracks from occurring in the circuit films CF1-1 and CF2-1 during accommodation, transfer, or holding.

The second inner side surface F2A-5 of the second connection portion F2-5 shown in fig. 9C may correspond to the second inner side surface F2A-2 of the second connection portion F2-2 shown in fig. 6A and 6B. The inclined surface G1 and the second inner side surface F2A-5 of the second connection portion F2-5 may form a fifth angle θ 5 therebetween. According to an embodiment of the inventive concept, the fifth angle θ 5 may be 90 degrees. Accordingly, when the angle between the rear surface PB-1 of the display panel DP1-1 and the second side surface S2-1 of the stacked display module DM1-1 or between the rear surface PB-2 of the display panel DP2-1 and the second side surface S2-2 of the display module DM2-1 is 90 degrees, the contact area between the second inner side surface F2A-5 and the second side surface S2-1 of the display panel DP1-1 or the second side surface S2-2 of the display panel DP2-1 may be increased to disperse the impact due to the slip. As a result, the display modules DM1-1 and DM2-1 may be stably received in the receiving member FS-5.

The support member PP-2 shown in fig. 9D may correspond to the support member PP-1 of fig. 6C. As shown in fig. 9D, the support member PP-2 may be disposed on the second inner side surface F2A-5. The second side surface S2-1 of the display panel DP1-1 and the second side surface S2-2 of the display panel DP2-1 of fig. 9C may be in direct contact with the second inner side surface F2A-5, and thus an impact generated from the outside may be directly transmitted to the second side surface S2-1 of the display panel DP1-1 and the second side surface S2-2 of the display panel DP 2-1. According to the present embodiment, an impact generated from the outside can be reduced by the support member PP-2, and thus the reliability of the display module assembly WS-5 can be improved.

According to embodiments of the inventive concept, a display module assembly in which a display module is stably received in a receiving member including a tilt portion and a seat portion can be realized or provided, and thus, retention reliability and stability can be improved.
