To provide a display label having excellent heat resistance and moisture absorption resistance.

The display label having a printing layer on one surface of a supporting base material and a tacky adhesive layer or adhesive layer on the other surface is characterized in that, (1) the supporting base material consists of a liquid crystal polymer indicating optical anisotropy in melting, (2) as described in (1) the normal heat-resistant temp. of the liquid crystal polymer indicating the optical anisotropy in melting is ≥140°C, (3) as described in (1) or (2), the solder heat resistant temperature of the liquid crystal polymer indicating the optical anisotropy in melting is ≥250°C, (4) as described in any of the (1) to (3) described above, the moisture vapor transmission rate of the liquid crystal polymer indicating the optical anisotropy in melting is ≤1.0 g/m2.24 hr, (5) as described in any of the (1) to (4) described above, the percentage of the water absorption of the liquid crystal polymer indicating the optical anisotropy in melting is below 0.2%.
