     Thus, in the light shielding member BM, the first portion PP 1  disposed between the first light emitting area PXA-R of the first pixel row PXL 1  (refer to  FIG.  4   ) and the first light emitting area PXA-R of the second pixel row PXL 2  (refer to  FIG.  4   ) spaced in the second direction DR 2  (the row direction) may have the first thickness TH 1  at the first edge EG 1  adjacent to the first light emitting area PXA-R of the first pixel row PXL 1  and the second thickness TH 2  at the second edge EG 2  adjacent to the first light emitting area PXA-R of the second pixel row PXL 2 . 
     Also, in the light shielding member BM, the second portion PP 2  disposed between the first light emitting area PXA-R of the first pixel row PXL 1  and the second light emitting area PXA-G of the first pixel row PXL 1  spaced apart in the first direction DR 1  (the row direction) may have the first thickness TH 1 . 
     In  FIG.  4   , for convenience of explanation, the area having the second thickness TH 2  in the light shielding member BM is hatched by a dark color, and the area having the first thickness TH 1  in the light shielding member BM is hatched by a pale color. As illustrated in  FIG.  4   , the portion having the second thickness TH 2  in the light shielding member BM may extend in the first direction DR 1  and is arranged along the second direction DR 2 . The portion having the second thickness TH 2  in the light shielding member BM may be adjacent to one side surface of each of the first to third pixel areas PXA-R, PXA-G, and PXA-B, and the portion having the first thickness TH 1  in the light shielding member BM may be adjacent to the other side surface of each of the first to third pixel areas PXA-R, PXA-G, and PXA-B. For example, in an embodiment of  FIG.  4   , the portion having the second thickness TH 2  is adjacent to an upper side surface (e.g., in the second direction DR 2 ) of the first to third pixel areas PXA-R, PXA-G, and PXA-B and the portion having the first thickness TH 1  is adjacent to a lower side surface (e.g., in the second direction DR 2 ) of the first to third pixel areas PXA-R, PXA-G, and PXA-B. 
     However, embodiments of the present disclosure are not necessarily limited thereto. 
     The light shielding member BM according to an embodiment of the present inventive concept may block light provided at a specific angle because the inner surfaces surrounding the side surfaces of each of the first to third pixel areas PXA-R, PXA-G, and PXA-B have different thicknesses. 
     For example, as illustrated in  FIG.  5 B , light emitted to a first path L 1  of the light generated from the light emitting device OLED may be provided to the display surface DP-IS (refer to  FIG.  1 A ) without interference of the light shielding member BM. However, light emitted to a second path L 2  may be blocked by the second partition wall P 2  having the second thickness TH 2 . Thus, an amount of the light emitted in a direction toward the second partition wall P 2  of the light generated from the light emitting device OLED may decrease. 
     According to an embodiment of the present inventive concept, the light shielding member BM may block light pro vied at a specific angle and simultaneously prevent color mixture between the adjacent light emitting areas providing light having different colors.

A portion adjacent to the first edge EG 5  may have a first thickness TH 5  less than a second thickness TH 6  of a portion adjacent to the second edge EG 6 .

     According to an embodiment, a side surface CS-C connecting the first edge EG 5  and the second edge EG 6  may include a curved surface having a thickness varying from the first thickness TH 5  to the second thickness TH 6 .

     The display panel DP-a according to an embodiment of the present inventive concept may include a light shielding member to solve a limitation in which the light provided from the display unit of the display panel DP-a is reflected by the front glass FW.

     According to an embodiment of the present inventive concept, as the path of the light provided at a specific angle is blocked, the limitation in which the light provided from the display panel DP-a is reflected by the front glass may be solved. Also, a process and a cost associated with attaching a separate member (e.g., a film, etc.) for light shielding may be obviated. 
     Referring to  FIGS.  14 A and  14 B , the display panel DP-b according to an embodiment of the present inventive concept may include a display module DM disposed in a display apparatus EA.

     In an embodiment, the window panel WA may include an optically clear insulating material. For example, the window panel WP may include glass or plastic. The window panel WP may have a multilayer structure or a single layer structure.

For example, in an embodiment the transmission area TA may have a visible light transmittance of about 90% or more. A bezel area BZA may have a relatively lower light transmittance than that of the transmission area TA. The bezel area BZA may define a shape of the transmission area TA. The bezel area BZA may be disposed adjacent to the transmission area TA and surround the transmission area TA (e.g., in the first and/or second directions DR 1 , DR 2 ). 
     The display module DM may display an image and sense an external input. The display module DM may include a display surface DP-IS including an active area AA and a peripheral area NAA. The active area AA may be activated by an electrical signal. 
     In an embodiment, the display panel DP-b may include a display unit DU-b and an input sensor ISL-b. The display unit DU-b and the input sensor ISL-b of the display panel DP-b may correspond to the display unit DU-A and the input sensor ISL described in  FIG.  8   . 
     The driving circuit DC may be electrically connected to the display panel DP and the input sensor ISL. The driving circuit DC may include a main circuit board MB and a flexible circuit board CF. 
     The flexible circuit board CF may be electrically connected to the display panel DP-b. The flexible circuit board CF may connect the display panel DP-b and the main circuit board MB. However, embodiments of the present inventive concept are not necessarily limited thereto. For example, in an embodiment, the flexible circuit board CF may not be connected to the main circuit board MB. The first circuit hoard CF 1  may be a rigid substrate. 
     The flexible circuit board CF may be connected to pads (e.g., display pads) of the display panel DP-b, which are disposed on the peripheral area NAA. The flexible circuit board CF may provide an electrical signal for driving the display panel DP-b to the display panel DP-b. The electrical signal may be generated from the flexible circuit board CF or the main circuit board MB. 
     The main circuit board MB may include all sorts of driving circuits for driving the display module OM or a connector for power supply. The main circuit board MB may be connected to the display module DM through the flexible circuit board CF. 
     The housing HU may be coupled with the window panel WP. The housing HU may be coupled with the window panel WP to provide a predetermined inner space. The display module DM may be accommodated in the inner space. 
     The housing HU may include a material having a relatively high rigidity. For example, in an embodiment the housing HU may include a plurality of frames and/or plates, which are made of glass, plastic, metal or a combination thereof. The housing HU may stably protect components of the display apparatus EA accommodated in the inner space from an external impact.
