[0080] The circuit board FPCB may process various signals input from the printed circuit board and output the processed signals to the display panel DP. For example, one end of the circuit board FPCB may be attached to the display panel DP, and the other end of the circuit board FPCB facing the one end may be attached to the printed circuit board. The circuit board FPCB may be connected to each of the display panel DP and the printed circuit board by a conductive adhesive member (e.g., an anisotropic conductive film).
[0081] The driver DIC may be mounted on the circuit board FPCB. The driver DIC may be, for example, an integrated circuit (IC). The driver DIC may include a panel driver and a fingerprint detector.
[0082] The panel driver may supply a data signal corresponding to the image data signal to the sub-pixel PXL while sequentially scanning the sub-pixel PXL.

[0085] In the fan-out area FTA, the first line LP1 may be positioned at both sides of the second line LP2. For example, the second line LP2 may be positioned at the center of the fan-out area FTA to correspond to the second area DA2, and the first line LP1 may be positioned at the edge of the fan-out area FTA to correspond to the first area DA1. In other words, the second line LP2 may be positioned at the inner side of the fan-out area FTA, and the first line LP1 may be positioned at the outer side of the fan-out area FTA. Therefore, the first line LP1 and the second line LP2 may be separated from each other in the fan-out area FTA.

The second pad portion PDP2 may be positioned at the center of the pad area PDA to correspond to the second line LP2, and the first pad portion PDP1 may be positioned at the edge of the pad area PDA to correspond to the first line LP1.

The horizontal connection line may be electrically connected to the seventh readout line RX7 disposed in the second area DA2 through the fourth contact hole CH4. The first connection line CNL1 may electrically connect the seventh readout line RX7 and the 1b line LP1b to each other.

The horizontal connection line may be electrically connected to the fifth readout line RX5 disposed in the second area DA2 through the fourth contact hole CH4. The third connection line CNL3 may electrically connect the fifth readout line RX5 and the 1f line LP1f to each other.

The horizontal bridge line may be electrically connected to the first data line D1 disposed in the first area DA1 through the second contact hole CH2. The first bridge line BRL1 may electrically connect the first data line D1 and the 2e-line LP2e to each other.

The horizontal bridge wire may be electrically connected to the second data line D2 disposed in the first area DA1 through the second contact hole CH2. The second bridge wire BRL2 may electrically connect the second data line D2 and the 2c line LP2c to each other.

[0206] According to the above-described embodiment, the first pads P1 electrically connected to the readout line may be disposed in at least one predetermined area to be disposed adjacent to each other without any intervening second pads, and the second pads P2 electrically connected to the data line may be disposed in at least one predetermined area to be disposed adjacent to each other without any intervening first pads. For example, the second pad portion PDP2 may be positioned at the center of the pad area PDA to correspond to the second area DA2 of the display area DA, and the first pad portion PDP1 may be positioned at both edges of the pad area PDA to correspond to the first area DA1 of the display area DA. The phenomenon that the sensing signal of the light sensing pixel PSR transmitted to the driver DIC through the first pad portion PDP1 is affected by the data signal transmitted to the data line through the second pad portion PDP2 may be reduced or prevented. In addition, the phenomenon that the data signal transmitted to the data line through the second pad portion PDP2 is affected by the sensing signal of the light sensing pixel PSR transmitted to the driver DIC through the first pad portion PDP1 may be reduced or prevented. In the case where the readout pads electrically connected to the readout lines and the data pads electrically connected to the data lines are alternately arranged in the pad area PDA, coupling capacitance (or parasitic capacitance) may occur between the readout pads and the data pads. Therefore, in the above-mentioned embodiment, the first pad portion PDP1 and the second pad portion PDP2 are arranged to be spaced apart from each other and each is positioned in a specific area of the pad area PDA, so that the above-mentioned coupling capacitance can be prevented, thereby improving the reliability of the display device DD.
[0207] According to the above-described embodiment, the first lines LP1 electrically connected to the readout lines may be disposed adjacent to each other in at least one predetermined area without any intervening second lines LP2 in the fan-out area FTA, and the second lines LP2 electrically connected to the data lines may be disposed adjacent to each other in at least one predetermined area without any intervening first lines LP1 in the fan-out area FTA. For example, the second line LP2 may be positioned at the center of the fan-out area FTA to correspond to the second area DA2 of the display area DA, and the first line LP1 may be positioned at both edges of the fan-out area FTA to correspond to the first area DA1 of the display area DA. The phenomenon that the sensing signal of the light sensing pixel PSR transmitted to the first pad portion PDP1 through the first line LP1 is affected by the data signal transmitted to the data line through the second line LP2 may be reduced or prevented. In addition, the phenomenon that the data signal transmitted to the data line through the second line LP2 is affected by the sensing signal of the light sensing pixel PSR transmitted to the first pad portion PDP1 through the first line LP1 may be reduced or prevented. In the case where the readout fan-out lines electrically connected to the readout lines and the data fan-out lines electrically connected to the data lines are alternately arranged in the fan-out area FTA, coupling capacitance (or parasitic capacitance) may occur between the readout fan-out lines and the data fan-out lines. Therefore, in the above-mentioned embodiment, the first line LP1 and the second line LP2 are arranged to be spaced apart from each other or not alternate with each other, and are each positioned in at least one predetermined area of the fan-out area FTA, so that the above-mentioned coupling capacitance can be prevented, thereby improving the reliability of the display device DD.

The vertical bridge wire may be electrically connected to the horizontal bridge wire of the first bridge wire BRL1 through the first contact hole CH1. The horizontal bridge wire may be electrically connected to the seventh data line D7 disposed in the first area DA1 through the second contact hole CH2. Therefore, the data signal transmitted from the driver DIC to the 2b-line LP2b may be transmitted to the seventh data line D7 via the first bridge wire BRL1.
